Duet 3 Expansion 1HCL is an expansion board connected via CAN-FD and is designed to provide a high-current stepper motor driver combined with multiple position feedback (encoder) interfaces. It has a number of peripheral inputs and outputs for functions such as motor temperature sensing, brake control and axis stop. It connects to the Duet 3 CAN-FD network using RJ11 connectors (the same as the Duet 3 6HC motherboard, Duet 3 expansion boards and axis distribution board). Multiple 1HCL boards can be cascaded on the same channel, with power (up to 48V) supplied locally. This allows very large machines to be built without significant wiring load and signal integrity issues.
Here are the main features at a glance:
- ARM Cortex-M4F microcontroller running at 120MHz.
- An advanced driver stepper TMC2160A: SPI control, can run in open or closed loop mode. Maximum motor current 6.3A peak per phase (4.45A RMS).
- Two medium current outputs (recommended 2.5A maximum) at VIN or VBRAKE voltage with PWM capability.
- Two 3.3V level outputs with PWM capability (3mA maximum)
- Two digital inputs
- One thermistor/PT1000 input
- 12 to 48V power supply input
- 12V, 5V and 3.3V regulators
- CAN-FD interconnection to the main control board and other expansion boards
Package contains: 1 x Duet 3 Expansion 1HCL

The item you will receive may differ in some features from the one depicted in the photo, depending on the production batch. Despite this, functionality is maintained.
Salve, chiedo gentilmente se alla scheda Duet 3 Expansion 1HCL si può collegare un encoder lineare (riga ottica), se non è possibile c'è un'altra scheda che può farlo?
Encoder compatibili con la scheda in base alla versione del firmware che si utilizza:
RRF 3.4 supporta solo encoder ad albero per motori in quadratura.
RRF 3.5 supporta anche gli encoder magnetici ad albero e gli encoder lineari.
