Basically a hack pad but with a lot more keys and a lot more LEDs.
Made because a hackpad was too easy and small. Also I wanted to make it more like a keyboard than a hackpad. I also wanted to use a full pico.
- 100 keys
- OLED Display
- Barrel Jack Power (Pico power is not enough)
- Auto Polarity Correcting Circuit for Barrel Jack
- 100 Neopixels
- External Power Supply for Neopixels (To run them at full brightness 😈)
