MyKritaPad is a custom 9-key macropad powered by a Seeed Studio XIAO RP2040! It includes 9 mechanical switches wired through 9 diodes and two EC11 rotary encoders for additional input control. ⭐
I wanted to try something completely new that I had never done before. I was very interested in how everyone can create their own mini keyboard, so I tried it too.
I started on Friday, October 28th. That day I saw that I could make my own mini keyboard, I registered and downloaded the programs. Then I opened KiCad and told myself that I would never do it (it was like flying a plane for the first time). Well, I had to overcome myself and started creating with it. At first it was terrible, but somehow I got over it.
Unfortunately, on October 29th I got sick and couldn't do anything at all, but on November 30th I overcame myself and started creating the first designs for my KritaPad. When I created it with it, I moved to Fusion, which I also looked into, what it was... Somehow I did it, even though I don't want to think about it.
Then on December 1st I overcame myself and spent the whole day at the computer to finish it. In the evening I finished and submitted the project.
- 9 mechanical keys
- 9x diodes for proper key isolation
- 12x SK6812 MINI-E addressable RGB LEDs (RGB LEDs unfortunately I had a bad footprint and because of that my neopixels don't work)
- 2x EC11 rotary encoders
- Powered by Seeed Studio XIAO RP2040
- Designed for use with KMK or custom firmware
The PCB is designed in KiCad and includes:
- 9 key switch footprints
- diode matrix wiring
- daisy-chained SK6812 MINI-E LEDs
- pins for two rotary encoders
- XIAO RP2040 as the main controller
(I know, it's terrible.)
The macropad can be programmed using KMK,... or any custom RP2040 firmware.
- 1x Custom PCB
