Custom Triple H-Bridge (DRV8874) with current feedback. SAMD21 Arduino Zero Compatible Controller. RS485, UART, Qwiic I2C, EEPROM I2C, USB and H-Bridge Temp Sensor.

3D printed housing and fingers. RN-42 Bluetooth Controller, OLED display and 2S LiPo.

Missing Decimal place for the Current.

5-Pin connector for the servo. Motor +, Motor -, 3V3, 0V & Pot feedback.

I had some problems with Pin Mapping on the SAMD21 so there are wire links for the UART-TX and RX lines and the REF Pin can't be used as an Analog Input pin.
