DRV8818EVM: 2.5A, 8 ~ 30V, BiPolar Driver

Summary

The DRV8818EVM is a complete solution for evaluating the DRV8818 micro-stepping, bipolar stepper driver. It includes a USB link to provide easy control from a personal computer (PC), a MSP430 microcontroller that interprets serial commands from the PC and generates control signals to the driver device, and the DRV8818 device with access to all signals for a complete evaluation.

The DRV8818EVM uses a combination of terminal blocks and test clips for the application and monitoring of power. The only power rail that the user must supply is VM for the device’s power stage. VDD for logic levels is internally generated from the USB connection. Users must apply VM (8 V to 35 V) according to data sheet recommended parameters.

Every pin on the device has been brought out to a test stake. A label on the silkscreen identifies each signal.
