2. Soldering the headers
3. Plugging the board in
Once you have soldered the headers your
board is ready to be placed into the desired
mikroBUS socket. Make sure to align the cut
in the lower-right part of the board with the
markings on the silkscreen at the mikroBUS
socket. If all the pins are aligned
correctly, push the board all the
way into the socket.
Turn the board upward again. Make sure
to align the headers so that they are
perpendicular to the board, then solder the
pins carefully.
Turn the board upside down so that
the bottom side is facing you upwards.
Place shorter pins of the header into the
appropriate soldering pads.
Before using your click board, make sure
to solder 1x8 male headers to both left and
right side of the board. Two 1x8 male headers
are included with the board in the package.
4. Essential features
Maxim’s DS2438 Smart Battery Monitor
integrates a temperature sensor, a timer,
an ADC to measure the battery voltage and
current, and a current accumulator that
monitors the total amount of current going
into and out of the battery. Also, 40 bytes of
EEPROM is available for storing important
parameters about the battery (chemistry,
capacity etc.). Several units can work on a
same 1-Wire bus because each DS2438 has a
unique ID. The MCP73831 has a programmable
charge current from 15 to 250 mA.

Charger click carries both a battery charger
controller and a battery charge monitor.
The smaller chip is MCP73831, a miniature
single-cell Li-Ion and Li-Polymer charge
management controller. The larger IC is
DS2438, a smart battery monitor. The
monitor communicates with the target MCU
through a 1-Wire interface. The battery
connector is on top of the board. Charger
click is designed to use a 5V power supply.
