Question: How to use this module to develop sensorless BLDC drivers?
Answer: The DRV8302 motor drive module has a three-phase back electromotive force BEMF output, which can be used for sampling commutation signals.
Question: Does it support ST FOC library?
Answer: In addition to the two internal current amplifiers of the DRV8302 driver board, three external current amplification circuits are designed to support the ST FOC library's three resistor current sampling method.
