DueX 5 channel expansion board 

- 5 x Additional TMC 2660 stepper motor drivers with stall notification

- 5 x Additional extruder heater outputs 

- 5 x Servo outputs with 5V power and 5V signal levels, sharing control channels with the heaters, this allows you to repurpose unused heater channels to drive servos

- 5 x Additional endstop inputs with indicator LED’s and 3.3/5V voltage selection. These are also usable as outputs.

- 5 x Additional controlled fan outputs, these can also be used for driving LEDs etc. The output voltage can be switched between 5V, 12V and VIN

- 4 x General purpose uncommitted I/O pins 

- 12V Switching regulator, for generating a 12V supply for fans, LEDs etc. This is for when VIN power is higher than 12V.

- 5 x Additional thermistor inputs.

- Support for 2 more thermocouple or PT100 daughter boards, supporting up to 4 more sensors.

- Optional 5V external power input for powering servos, fans etc.
