2.3 EVM Hardware Quick-Start

This section describes the steps to prepare the DRV8334EVM for first motor spin-up. This section assumes the default jumper positions mentioned above are used.

  1. Plug the DRV8334EVM onto the upper position of the LAUNCHXL-F280049C board.
  2. Connect motor phase connections to their respective MOTA/MOTB/MOTC inputs on J13, making sure to match A, B, and C.
  3. Connect the Hall sensor connections, Hall power, and ground to J11. Make sure that Hall A, B, and C are in the correct order.
  4. Connect the provided micro-USB cable to the LAUNCHXL-F280049C.
  5. Connect VMOTOR and GND to connector J10. A low current limit of 300 mA on the VMOTOR supply is recommended for first power-up to verify the EVM is connected correctly. If there is no issue upon power-up, then the current limit can be raised to allow for current based on your motor specifications. VMOTOR range is 5 V to 60 V.
  6. Start the GUI per the instructions below in Section 3.1.
