2.3 Specifications

The DRV8844AEVM is preprogrammed with firmware for evaluation. A 10-pin connected is available onboard if user wants to reflash onboard MCU (MSPM0G1107) with customer firmware. A buck converter supplies 3.3V rail to power MCU from VM supply voltage. The J2 signal header uses removable shunts to pass the signals from the MCU to the motor driver. Remove any of these shunts to easily jump in external control signals to the driver. Provide an external motor power supply to the J4 screw terminal within the operating range of the device. The DRV8844A supports an 8V to 65V operating supply voltage range.
