It is a 60% wireless keyboard(bluetooth) also works wired. It has magnetic modules. Currently I only added a Numpad but almost anything could be added in a chain as long as it works on i2c.
it has hotswapable switches, rgb lights for each key, OLED, rotoary encoder, dedicated charging module(1000mah) and a 10000mah battery. Also it is kind of MCU agnostic, you can use any XIAO series MCU with it, for example rp2040 if you don't want bluetooth or nRF52840.
I used shapr3d to make the case, it is not done, I am still working on it, once I am happy with a case I will add it here, but the current case is as follows:
The charging module and battery are not connected to the PCB electrically, I will use wires for them.
I used KiCad to make the PCB. Here are the schematics:
Here is the PCB:
For Firmware I made two versions:
- QMK Firmware: Works out of the box but it is wired only (no Bluetooth). This is ready to use.
- ZMK Firmware: Supports Bluetooth wireless functionality. This will work only when ZMK is upgraded to Zephyr 3.6 or with a custom driver for the I2C expander.
Both firmware options are available in this repository under the Firmware directory.

Important Note: You might find some of these components cheaper on AliExpress, but trust me, their shipping costs to Pakistan are absolutely insane. I created this BOM keeping Pakistani shipping costs in mind - sometimes paying a bit more upfront is way better than getting hit with crazy shipping fees later. If you're in a different country, definitely check AliExpress for better deals, but for us Pakistanis, this is probably your best bet cost-wise.
Also Ali Express prices tend to change for different regions, so when verifying the BOM, make sure to set the region to Pakistan to get the correct prices.
