This board allows for the connection of up to 4 Duet 3 Toolboards to the Duet 3 Mainboard at one time, greatly simplifying the CAN-FD bus and power wiring.
Tool board power outputs are individually bused, and the CAN-FD bus connections can by bypassed if less than 4 tools are connected.
These can be connected to other Duet 3 CAN-FD bus expansion boards (or other tool distribution boards) via the RJ11 connector for CAN-OUT.
CAN IN – RJ11.
12-32V VIN distributed to 4x power out via 4x 5A fused.
