The USB to 4-Channel 485 Module is Unitree Robotics' multi-port RS-485 adapter for running up to four separate motor buses from one computer. It connects to the host over USB Type-C (USB 2.0) and appears as four serial ports (an FTDI FT4232H device; ttyUSB0 to ttyUSB3 on Linux). Each channel has a GH1.25-3P connector carrying A, B and GND, send and receive LEDs and its own isolation protection. Unitree positions it as the one adapter needed for 12 to 18-joint robots such as quadrupeds and humanoids, and its actuator SDK drives GO-M8010-6 motors through it directly. It is the communication module in Unitree's Package 2 kit for the IM6014.
