Duet 3 Expansion Board 1HCL (ARM Cortex M4F @120 Mhz, TMC2160A)

Expansion module for Duet 3 with a dedicated 32 Bit Processor (ARM Cortex M4F @120 Mhz). It includes an advanced TMC2160A stepper driver that is SPI controlled and can operate in either open loop or closed loop mode. Connectivity is provided by RJ11 CAN In and CAN Out connectors to link to the Duet 3 CAN-FD bus. IO headers supply both 5V and 3.3V for low-current external devices — Maximum 300mA at 5V (3.3V is converted from 5V so if using 3.3V externally the 5V limit is reduced). A jumper is provided to force the bootloader to request a firmware update from the Duet 3 main board.
