Problem with Simple FOC

Hello,

I’d like to use this gimbal motor, the “GBM2804H-100T Gimbal Motor.” To do so, I ordered the “Simple FOC ESP 32 FOC” board. However, since there’s hardly any documentation available for this specific board, my question is: How can I control the motor and program this board using my computer? The chip on the board has a Wi-Fi and a Bluetooth logo, but when I power the board with 12 V, it isn’t recognized.

Thank you very much

There should be separate ports to power the board with 3.3V somewhere. I'd guess you're not powering the microprocessor with the same voltage as the motor, since it would 'steal' the motor's voltage and wouldn't be stable. Look for "VIN" pins, or if there aren't any, maybe try to power it via one of the 3V3 ports (while the power to the motors is disconnected at first of course). Maybe some LEDs will light up, and you'll know it's on.

I’m not sure if the MCU is pre-flashed, so you could send your code over WiFi. Your best chance to talk to the board is using an FTDI or CH340 adapter board which is a USB to serial interface.
The serial pins TX,RX and GND are on the header below the ESP32 chip.
