CHAPTER 2: DEVICE DESCRIPTION
2. Introduction to the chapter
This chapter features explanation of the interfaces visible to the user. Most of the time those would
be the only parts of the PIC-KIT3 that the user manipulates or contact with.
2.1 Ports and connectors
The user can freely access the USB and the ICSP connectors available. There is also a power jack
near the USB. The pinouts and the usage of those are discussed below.
2.1.1 USB Standard-B connector
The USB type B connector follows the USB 2.0 specification. The connector itself looks
like this:
2.1.2 ICSP connector
The pinout of the ICSP connector (note that the cable after it might change the signals) is
shown below below:
Page 6 of 15
OLIMEX© 2017 PIC-KIT3 user's manual
2.1.3 Power jack
The Olimex PIC-KIT3 has additional power jack which comes handy in field programming
situations where you lack mini USB cable, but you have access to external power.
The power jack should receive between (6-9)V DC and it is practical to already have an
image uploaded in the PIC-KIT3 before using the power jack.
The inner pin is the VDC, the outer plate is the GND.
Please notice that previous hardware revisions of Olimex PIC-KIT3 allowed up to 12V DC
applied to the power jack, however this is NO LONGER the case. Applying 12V DC to the
power jack would damage PIC-KIT3!
2.2 Status LEDs
PIC-KIT3 has two LEDs – yellow one named ACTIVE and a double-color (red/green) one named
STAT.
The yellow LED shows USB activity – e.g. when the device is connected to the USB properly;
when you are powering the board from external source via the power jack this LED would blink.
The STAT LED shows RED color when you are connected to MPLAB or the image inside the flash
memory is ready for operation. When there is programming data transferred the double LED should
blink in orange color (red and green).
2.3 Programmer-to-go button
The button allows you to program a device with a single button press with a binary image stored in
the internal flash memory of PIC-KIT3. Storing the image inside is done via MPLAB.
The small black button near the USB Standard-B connector is used to program target devices with
the binary image stored in the 512k Flash. This function works fine together with the power jack
which allows easy operation when a power supply is available nearby without the need of a
computer or USB power supply.
The programmer-to-go button is also used to enter bootloader mode. You would never need to use
bootloader mode, when the unit is operating as expected. However, the bootloader mode might
come in handy for firmware recovery. To enter bootloader mode:
1. Disconnect PIC-KIT3 from the USB cable.
2. Press and hold down “programmer-to-go” button.
3. Connect PIC-KIT3 to the USB cable.
4. Release “programmer-to-go” button.
Note! There is a bug when using programmer-to-go button without an image stored in the PIC-KIT3
flash memory. This bug might occur if using a PIC32 target chip which might leave it in
unrecoverable state. It is advisable to always ensure there is an image in the PIC-KIT3 (from
MPLAB interface). Be especially careful with the button when handling PIC32 targets.

2.3.1 Programmer-to-go in MPLAB 8
Once you connect the device as explained in CHAPTER 3 (respectively for MPLAB 8), and
you have selected the “PICKit 3” in programmer menu, go to “Settings”. Click on the
Programmer-to-go tab and “Send Image in Memory”. You need to have a ready image either
by importing a binary (hex), reading such from the target device or by building the current
project.
2.3.2 Programmer-to-go in MPLAB X
First make a standard project or import binary file
using the recommended settings.
Then you have to add the 'Programmer To Go
PICKit3 Main Project' button to the debugger
toolbar. You can do this by right-clicking on any
empty toolbar space (up at the top of the IDE). A
popup menu will appear. Choose the Customize
menu item to get the Customize Toolbars dialog.
Scroll down to the Project folder and select the
first icon there (the Programmer To Go PICKit3
Main Project icon). Drag it to the debug tool bar
(the one with the green run arrow). Close the
menu. Finally, press this button and it will invoke
the programmer-to-go feature.

CHAPTER 3: SETTING UP PIC-KIT3
3. Introduction to the chapter
More details about the standard connection routine of Olimex PIC-KIT3 and your target via
MPLAB 8 and MPLAB X.
3.1 Hardware setup
The required hardware for successful connection might vary depending on the target board and
chip.
PIC-KIT3 has a 6-pin male DIP header with 2.54mm (0.01'') pitch.
1) The first thing to consider is the target's connector's type. Some of the older boards have RJ11
connector. Some boards have connectors with smaller step (0.05'' distance between pins). For cases
like that an adapter might be created following the pinout. Alternatively, we sell adapter for cases
like this named PIC-ICSP: https://www.olimex.com/Products/PIC/Programmers/PIC-ICSP/.
If not using an already assembled board, please, refer the pinout of the connector of the debugger in
CHAPTER 2. Note the mirrored female-female ICSP cable that ships with the
programmer/debugger.
2) After the connection between the OLIMEX PIC-KIT3 and your target board is established you
need to connect the debugger to the computer. Note that this requires a USB standard-B to USB
standard-A cable which is not included in the package but might be purchased separately either
from your favorite electronics store or from our web site.
3) The final hardware note is to power the target chip/board. The PIC-KIT3 allows target powering
in the (3.0-3.5)VDC range with the standard amperage for USB 2.0 – 100mA maximum. If you
board exceeds these power requirements make sure it is sufficiently powered.
3.2 MPLAB 8
Connecting the programmer/debugger in
MPLAB 8.xx is fairly straightforward but it is
recommended to be done in the following order:
1. Start MPLAB 8.xx
2. Select target chip from “Configure” →
“Select Device”. Ensure the device selected is
supported by PIC-KIT3. If there is a green dot at the left side of PIC-KIT3 it is supported.
3. Select PIC-KIT3 either as a programmer (or a debugger) from “Programmer” → “Select
programmer” (or “Debugger” → “Select tool”)

(optional) 4. If asked for firmware update – allow it to download and do not disconnect while the
device is updating
(optional) 5. If you wish (and it is possible) you can power your target board/MCU via the PIC-
KIT3 from Programmer Settings Power Choose desired voltage and check the box.
6. Note! Before unplugging PIC-KIT from the computer, disconnect it from the MPLAB IDE by
navigating to “Programmer” → “Select programmer” (or “Debugger” → “Select tool”) and then
selecting “None”
7. You are now ready to start a new project, import a binary or debug existing project via the PIC-
KIT3.
Refer to the documentation available at Microchip's web site for more information on the MPLAB.
3.3 MPLAB X
1. Create a project or import a hex – a dialog window appears.
2. Choose the correct device and mark the PICKit3 as a hardware tool (if you miss that step when
the project is ready or you have opened a ready project – right-click over the project and go to
settings)

3. Click Next → adjust destination folders and names
4. Click Next → review the information and choose to Finish
(optional) 5. After the project is ready you adjust options by selecting and right-clicking over the
project name and going to the “Properties” option. Mark the PICKit3 entry and take a look at the
different drop-down options. You can set the power to the target board from there also.

CHAPTER 4: FREQUENTLY ASKED QUESTIONS
Q: What USB cable do I need?
A: You should have a USB type A-B cable to connect to PC, all PC USB hosts have USB-A
connector while PIC-KIT3 has USB-B connector so the cable should be USB A-to-B type. Note
that such a cable is not included in the package.
Q: Does your ICSP connector layout differ from the ICSP connector layout of the original PIC-
KIT3?
A: Yes. This can be easily adjusted by proper mirrored cable. Pay attention to the mirroring of the
cables that the Olimex PIC-KIT3 comes with. Note the layout at the connector also.
Q: What should I know when I connect PIC-KIT3 to a target board?
A: It's very important that your target PIC MCLR is not connected directly to VCC! During the
programming/debugging MCLR goes as high as 13VDC and if your target MCLR is connected
directly to the target's VCC you will blow either the PIC-KIT3 or your target board. Always use
10K pull-up resistor from MCLR to VCC.
Q: What are the LEDs for?
A: There are two LEDs – one yellow LED named ACTIVE and one double-color (red/green) LED
named STAT. The yellow LED shows USB activity, e.g. when the device is connected to the USB
properly; when you are powering the board from external source via the power jack this LED would
blink. The STAT LED shows RED color when you are connected to MPLAB or the image inside the
flash memory is ready for operation. When there is programming data transferred the double LED
should blink in orange color (red and green).
Q: What voltage should I provide to the power jack for “programmer-to-go” stand alone mode?
A: (6-9) V DC; the inner pin of the connector is the DC
Q: Hello, I pressed the "programmer-to-go" button and my PIC32 died. What burned my chip?
A: Do not use "programmer-to-go" button when there is no image in the OLIMEX PIC-KIT3 or
MICROCHIP PIC-KIT3 or that might put your microcontroller in an unrecoverable state. We have
tested the mentioned scenario and we can confirm it destroys PIC32 chips (using both our and the
original Microchip PICKIT3). We don't take responsibility if you brick your chip that way.
Q: Hello, I attempted to use PIC-KIT3 and then the connection failed. After this the PIC-KIT3 gets
listed with exlcamation mark in "Windows Device Manager" and reports the error - "This device
cannot start. (Code 10)". What is the problem? What should I do?
A: This problem might appear after a failed firmware update. The firmware update might fail due to
different reasons. It happens more frequently when you often change the versions of MPLAB that
you use (the latest PIC-KIT3 firmware versions in MPLAB 8 differ a lot from the latest PIC-KIT3
firmware versions in MPLAB X or MPLAB IPE).
There is a fix for this problem – enter bootloader mode – disconnect the PIC-KIT3 from the USB;
press and hold the small black button (programmer-to-go button); connect the PIC-KIT3 to the
USB; release the button. Then open MPLAB or MPLAB IPE and attempt the connection again.
Make sure you are using latest version of MPLAB IDE or MPLAB IPE.
Page 12 of 15
OLIMEX© 2017 PIC-KIT3 user's manual
If the connection still fails re-try the procedure at least few more times. Then try to manually
download the firmware (again enter bootloader mode using the button) and then go to "Settings" ->
"Manual Download Firmware". In MPLAB IPE you would need first enable "Advanced Mode"
before being able to select "Manual Download Firmware".
Test the same procedure (to manually download the firmware) without entering bootloader mode –
use a standard connect procedure (do not hold the button).
Finally, test the above fixes with another MPLAB version. For example, if you have used MPLAB
8, try with the latest MPLAB IPE; or if you have used MPLAB IPE, then try with MPLAB 8.92.
Sometimes closing-opening the software would allow you to perform the firmware update.
Sometimes you would need to try a few times until it succeeds.
Q: Hello, I use both MPLABX and MPLAB 8.xx. Recently, the "programmer-to-go" to go function
stopped working in MPLAB 8, everything else works fine. The error I get is: "PK3Err0033: 4 bytes
expected, 0 bytes received". What can I do?
A: This is a known problem that affects both the original Microchip PICKit3 and Olimex PIC-
KIT3. It was caused by the newest firmware released. Most typically the problem appears after you
have used new version of MPLAB X or MPLAB IPE. You PIC-KIT3 got automatically upgraded
with a firmware version that is no longer compatible with MPLAB 8. The versions incompatible
with MPLAB 8 are firmware versions 1.3x.xx and newer (1.35.16, for example). With such a
firmware you will not be able to make proper connections to targets after an AP update nor you
would be able to use programmer-to-go in any MPLAB prior ot MPLAB X. The PIC-KIT3 would
still work fine in MPLABX and MPLAB IPE (and the programmer-to-go would also work fine).
So if you want to use MPLAB 8 you would need to manually revert to firmware version 1.28.90 (or
any 1.2x.xx version). This can be done in MPLAB 8:
1. Navigate to Programmer -> Select Programmer -> PICKit3
2. Deal with any pop up message making sure there is some power to the PIC-KIT3; ignore any
reports for errors they doesn't matter at this point
3. Navigate to "Programmer" -> "Settings" (at the bottom); click "Configuration" tab; Disable
"Auto Download Latest Firmware" and click "Manual Download". Point the pop-up to
PK3FW_012890.jam (or similar as long as it is is located in the MPLAB 8 folders), by default
located in C:\Program Files (x86)\Microchip\MPLAB IDE\PICkit 3. Click "OK" and wait for
upload.
4. If there are problems or the update takes more than a few minutes disconnect the PIC-KIT3 from
the USB, connect it again and try the firmware update again. The procedure would refuse to work
sometimes if you don't reset the connection (by unplugging and pugging the PIC-KIT3 again).
5. Upon successful revert you would see "Firmware Suite Version...... 01.28.90" instead of
"Firmware Suite Version...... 01.35.16".
Now you can use MPLAB 8 as previously and the programmer-to-go button would work.
Q: My PIC16 can not be debugged. Why?
A: Some PIC MCUs might require additional headers to be able to debug them. Always check the
chip's datasheet for hardware requirements.

5.3 Product support
For product support, hardware information and error reports mail to: support@olimex.com. Note
that we are primarily a hardware company and our software support is limited.
Please consider reading the paragraph below about the warranty of Olimex products.
Warranty and returns:
Our boards have lifetime warranty against manufacturing defects and
components.
During development work it is not unlikely that you can burn your programmer
or development board. This is normal, we also do development work and we have
damaged A LOT of programmers and boards during our daily job so we know how it
works. If our board/programmer has worked fine then stopped, please check if
you didn't apply over voltage by mistake, or shorted something in your target
board where the programmer was connected etc. Sometimes boards might get
damaged by ESD shock voltage or if you spill coffee on them during your work
when they are powered.
Please note that warranty do not cover problems caused by improper use,
shorts, over-voltages, ESD shock etc.
If the board has warranty label it should be not broken. Broken labels void
the warranty, same applies for boards modified by the customer, for instance
soldering additional components or removing components – such boards will be
not be a subject of our warranty.
If you are positive that the problem is due to manufacturing defect or
component you can return the board back to us for inspection.
When we receive the board we will check and if the problem is caused due to
our fault and we will repair/replace the faulty hardware free of charge,
otherwise we can quote price of the repair.
Note that all shipping back and forth have to be covered by the customer.
Before you ship anything back you need to ask for RMA. When you ship back
please attach to it your shipping address, phone, e-mail, RMA# and brief
description of the problem. All boards should be sent back in antistatic
package and well packed to prevent damages during the transport.
