[title|Using servos and controlling unused IO pins]
 
[summary]RepRapFirmware allows you to connect other devices to outputs that are not required for their primary purpose. The Duex 2 and Duex 5 expansion boards for the Duet 2 WiFi and Ethernet also provide additional outputs.[/summary]

The miscellaneous pin numbers 60-63 correspond to the CS5-CS8 pins on the expansion connector. These were originally allocated for use as the E2-E6 endstop pins and are labelled as such on the expansion connector, but they are now used to address thermocouple and PT100 daughter boards on a Duex 2 or Duex 5 instead. Because most users don't need more than the four thermocouple and PT100 channels supported on the Duet 2, we make CS5-8 available as general purpose I/O if you do not have any daughter boards fitted to the Duex 2 or 5. Here

It will be helpful to refer to the wiring diagram for the [[Duet Wiring Diagrams|Duet 2 Wifi/Ethernet]] and the [[Duex wiring diagrams|Duex]] to identify the pins.

Here
is the mapping between pin numbers, signal names, and the labels on the expansion connector:
