# ChessPad!
### Inspiration
I came across this event just from a random email, and knew I had to try it out. The name was chosen quite randomly in the end though, and its only real implementation is as a symbol on the pcb
So much thanks goes to whoever made "Ducc's fidget toy". I even ended up stealing their BOM, with slight adjustments
### Extra info
None
### Specifications
BOM:
- 6x Cherry MX Switches
- 2x SK6812 MINI Leds
- 1x XIAO RP2040
- 6x Blank DSA Keycaps (preferably white or black, for that chess theme, but doesn't matter too much)
- 4x M3x16 Bolt
- 4x M3 Heatset
- 1x Soldering iron
- 1x EC11 Rotary Encoder
- 1x Case
- 1x EC11 Rotary Encoder
Others:
- KMK Firmware
- FrontPlate.step
- BackPlate.Step
