Duet 3 Expansion Board 1HCL

Duet 3 Expansion Board 1HCL The Duet 3 Expansion 1HCL is a CAN-FD connected expansion board that is designed to provide a high current stepper motor driver, combined with multiple interfaces for position feedback. It has a number of peripheral inputs and outputs for functions such as sensing motor temperature, controlling a brake and axis endstop. It connects to the Duet 3 CAN-FD bus using RJ11 connectors (the same as the Duet 3 Mainboard 6HC, Duet 3 Mainboard 6XD, Duet 3 expansion boards, and the tool distribution board). Multiple 1HCL boards can be daisy chained on the bus, with power (up to 48V) provided locally. This allows for very large machines to be constructed without a significant wiring burden and signal integrity issues. Hardware Overview
