X.Tips X7S Keyboard (2024-04)

QMK config

I've managed to compile a working firmware with this config: https://github.com/gleber/qmk_firmware/commit/54078ec73c0ff2bd01984242f748a837c1954d03

Details

This isn't tested much, just the basics: keys and split setup. LED, bootloader magic key and any other features are not yet implemented. Tested only the Miryoku layout so far.

I've disassembled it and found a few things.

Back of one of the sides looks like this:

A more close up photo of the chip shows some STM32 chip:

If you decode the QR code it gives you a short link to what seem to be JLC PCB page about this specific PCB:

• right: https://m-9.cn/2kx9vqhz04xv
• left: https://m-9.cn/2kx9vqu40dft

It includes product name 【X.Tips】X7S小分体键盘_-_V2.0_【热插拔】PCB-X7S-V2-R__20240726163326 which translates with Google Translate to 【X.Tips】X7S small split keyboard_-_V2.0_【Hot plug】PCB-X7S-V2-R__20240726163326

And these schematics images for the right side:

Attached via-x7.json file was sent to one of the buyers by the seller. It works for my keyboard.

At that time, I wrote down the following:

SWDIO=PA13=34, SWCLK=PA14=37, GND=VSS=8, NRST=7

To flash the keyboard you need to connect the reset contacts (not necessary the holes, but the metal around them) with anything conductive DURING power up of th
e keyboard. I.e. the way I do it normally is I short these RESET contacts and I plug in the USB cable. This moves the chip on the keyboard into bootloader mode, w
hich allows you to flash it.

Hope that helps
