Duet 3 Expansion 1HCL

In stock, ready to ship. Documentation can be found here. The Duet 3 Expansion 1HCL is a CAN-FD connected expansion board designed to provide a high current stepper motor driver, combined with multiple interfaces for position feedback. Duet 3 Expansion 1HCL High Current Loop Stepper Motor Controller​​​​​ The Duet 3 Expansion 1HCL 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 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. The documentation contains more details; a summary of the feature set is here: ARM Cortex-M4F microcontroller running at 120MHz. An advanced TMC2160A stepper driver: SPI controlled, can be run in open loop or closed loop mode. Maximum motor current 6.3A peak per phase (4.45A RMS). Two medium-current (2.5A max recommended) outputs at VIN or VBRAKE voltage with PWM capability Two 3.3V-level PWM capable output (3mA max), Two digital inputs One thermistor/PT1000 input 12 to 48V power input On-board 12V, 5V and 3.3V regulators CAN-FD interconnect to main controller board and other expansion boards As of May 12th, 2021, all Duet3D products purchased from Filastruder will be eligible for a 12-month limited warranty.
