From the project

RPI HAT for small/medium robots (IMU, Dynamixel)

- IMU over I2C - Dynamixel motor communication: both TTL and 485 to drive Dynamixel/Feetech motor (requires cable adaptation) - in/out audio device with an integrated mems microphone. Wago connectors allows connection of loudspeaker and extra microphone. - expension Qwiic connectors, 1 mm/3V3. Please refer to the schematic for knowing which can be use on you raspberry pi.
