This is a small extension board located on the CyberBot. It distributes the CAN-bus to all 6 cybergears and provides a debug port. Each cybergear CAN-bus sink can be switched between CAN-bus or debug port. The can-bus is designed as star topology, which works in small setups.
The switches are missing in the production files and you need to solder these on your own. The required switches are MSS22D18 Mini DIP Slide Switch 2x03.
The debug port is connected to a special CAN to USB adapter. There is no product number. I only could find one offer on Aliexpress for around 12 euros:
USB-TTL/RS232/RS485/CAN Serial Communication Module CH340 CP2102 Data Conversion
Transparent Transmission Standard Protocol
