Duet 3 Expansion Board 3HC is designed for situations where the mainboard does not provide enough stepper driver outputs or I/O for your system. The board includes 3 high-current stepper motor drivers, 3 high-current outputs, multiple PWM outputs, and extensive I/O options. This makes it possible to control even larger and complex motion systems with ease. They can be daisy-chained together via the CAN-FD bus, this makes it a scalable solution for large automation systems and multi-axis setups. Key Features Powerful Processing: ARM Cortex-M4F microcontroller for fast, reliable performance. High-Current Drivers: 3x TMC2160/5160 stepper drivers with advanced motion control features. Comprehensive I/O: Multiple PWM outputs and configurable I/O pins for wide application use. Duet 3 Family The Duet 3 family is built around a mainboard that acts as the central control unit. Functionality can then be expanded by connecting dedicated expansion boards through the CAN-FD ports, giving the flexibility to add extra stepper drivers, I/O, and specialised features such as closed-loop motor control. This modular approach makes it possible to scale a system to match the demands of the application. From compact setups to large, complex machines, the Duet 3 Family provides the flexibility to control extensive motion systems for aluminium extrusion setups, CNC machinery, and other advanced motion control applications.
