# Epad
This is my submission for Hackpad V2!
## Inspiration
I was inspired by a macropad that I saw in a YouTube video a while back. It looked really cool so I tried to replicate it as best as I could from memory.
## Challenges
My biggest challenge was getting everything to line up correctly. I know I spent a long time just getting every hole at the top lined up with the switches.
## Features
- 12x cherry mx keys
- 1x rotary encoder switch
- KMK firmware
## PCB

## CAD
Designed with Fusion 360. The guide helped a ton!

## Firmware
Made using KMK Firmware
## BOM
- 1 XIAO-RP2040
- 12x Cherry MX Switches
- 12x White keycaps
- 12x 35_SOD27_P7.62mm diodes
- 1x Rotary Encoder Switch
- 4x 8mm deep 3.332mm wide 4mm size m4x0.7 screws
- 1x knob for the rotary encoder
