A custom mechanical keyboard inspired by the CFTKB Mysterium.
This is a raspberry pi pico powered keyboard I designed as I wanted something similar to a CFTKB Mysterium but easier to solder and a bit more robustly designed.
Pre-compiled firmwares can be found here
1x Type-C-31-M-14
90x 1n4148 DO-35
90x MX keyboard switches (5 pin advised if without switch plate)
3x 5.1K 1/4W resistors
1x 3mm LED
1x 1x04 2.54mm pin socket (optional oled)
1x Panasonic EVQPU SMD switch (optional reset)
raspberry pi pico
10x m2 female standoffs 10mm
20x m2 screws <5mm
(this list may not be totally accurate since I often forget what has changed inbetween when the readme is updated.
Most part orientations should be marked on the PCB however it is important to note that you NEED to connect the pads under the MCU to the respective pads on the board for USB to work, you also need 5.1K resistors to work with USB PD compatible ports.
the type-c port may be difficult for some to solder so use loads of flux and minimal amounts of solder, its best to solder the large 4 outer pins of the shell first.
uh well why not, I think it would be a nice example for people to use as a example. When I came up with the idea of this keyboard there was 1 other raspberry pi pico keyboard so I decided it would be cool to make a keyboard.
