2.1 EVM Hardware Setup

TI provides LaunchPad™ development kits to evaluate MSPM0 Arm Cortex-M0+ micrcontrollers and evaluation modules (EVMs) to evaluate the DRV83xx family of brushless-DC motor drivers. These evaluation boards are available on ti.com and can be used as a system evaluation platform for sensorless FOC motor control.

For supported evaluation boards, refer to Section 2.1.1.

Note: The provided defaults have pre-configured pins that are intended to support hardware evaluation boards. If a custom PCB is used, refer to the following Pin Configurations sections to assign the supported pins for the 3-phase motor driver.
