Dual brushless FOC driver_ESP32 expansion board

The expansion board corresponding to the original dual-channel FOC controller project based on ESP32, dual-channel L6234 driver, realizes vector control of dual-channel brushless motors.

Please use this board with my ESP32 dual-channel FOC control board:

Let’s briefly talk about the board situation. Two L6234 are used as drivers, supporting 12V~24V power supply and with current detection (INA240). The theoretical peak current is 5A, and the average current should be limited to 3A. If the PCB only has 1oz of surface copper, the current will be smaller. If the power is high, it is best to add two heat sinks.

Let’s refer to the project in the link above for the remaining projects, so I won’t write them again.

2021.07.14 Update:

    The board is still in the testing stage. The current loop has just been adjusted to one channel. There may be some problems with the ina240 in the other channel. I will let you know when the test is completed. If you are anxious, you can make a sample and test it yourself first~
