Main control chip: stm32f103c8t6/cbt6 will do
describe:
1.stm32 master control + Bluetooth HID module 2.type-c interface can use lithium battery 3. Symphony ARGB!!!!!! 4. The function is a digital keypad that can only modify the key values 5. Low cost, do it yourself All open source programs cost only 60+ yuan each. 6. Hot-swappable (buy a hot-swappable axis seat)

The size of the board is 10x10, just so that I can go to Jialichuang for 5 yuan for proofing.
Key combination description
1. ESC + . to switch Bluetooth/USB mode
2. ESC + turn on/off the running light in the lower left corner
3. ESC + upper right corner to switch LED light
4 ESC + third from the bottom in the lower right corner (third from the top): Modify the effect of the running water lamp
5. ESC + the second to last one in the lower right corner (fourth from the top): Modify the effect of the running water lamp
The default state is running water light
ESC + - to switch lighting effects
ESC + . Switch USB or Bluetooth
The lighting effect of U will be displayed when switching to USB
When switching to Bluetooth, B's light will be displayed (although it doesn't look like B, I tried to make it look like B)
)
ESC + .> and ESC+9 (.> the one above in the picture). That key can adjust the color effect of the running water lamp.
Close-up of the back of the board (the one you are proofing does not have an OLED interface because I deleted it later and the board is too small to fit the OLED screen)
For the Bluetooth HID module, it is recommended to buy a 1.27mm pin header for suspended soldering. If you buy a 2.54mm one, it will be troublesome to remove the black rubber cover.
Because I can't afford steel plates, I can only use steel plates to beat PCB wood. It is recommended to make thin ones, not 1.6mm. The thinner, the better the installation. Of course, if there are more than 5 pieces of proofing, don't make them.
That’s it, done! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! !
