<p>This macropad is a great introduction into programming and soldering. Follow the guide on&nbsp;<a href="https://www.tomshardware.com/how-to/raspberry-pi-pico-powered-stream-deck">tomshardware.com/how-to/raspberry-pi-pico-powered-stream-deck</a>&nbsp;to for example wiring and software.</p><p>Sample code has been provided - in the link above.&nbsp; Keycodes can be found here:&nbsp;<a href="https://circuitpython.readthedocs.io/projects/hid/en/latest/_modules/adafruit_hid/keycode.html">circuitpython.readthedocs.io/projects/hid/en/latest/_modules/adafruit_hid/keycode.html</a></p><p>Parts List:</p><p>-18 cherry style mechanical key switches<br>-raspberry pi pico<br>-wires<br>-no glue or screws required! all parts friction fit together</p><p>Assembly:</p><p>-Print keycaps, frame, and switch plate<br>-snap all switches into the plate<br>-solder a common wire between one pin on each switch<br>-solder a wire between the 3v3 pin on the pico and the power bus on the key matrix<br>-solder the remaining pins of the switches to an individual gp pin on the pico (I've used gp0-17, but you can use any - just change it in the code)<br>-snap the pico onto the standoffs in the frame<br>-slide the switch plate into the frame</p>
