description:
1. Stm32 main control + Bluetooth HID module 2. Type-c interface can use lithium battery 3. Symphony ARGB !!!!!! 4. Function is the numeric keypad can only be programmed to modify the key value 5. Low cost, do it yourself One is 60+ yuan open source source program is open source 6. Hot plug (buy hot plug shaft seat)

The size of the board is 10x10 , just to be able to make samples at Jiali Chuang for 5 yuan
Schematic diagram
PCB 3D preview:
Combination keys
1. ESC +. To switch Bluetooth/USB mode
2. ESC + turn on/off the water light in the lower left corner
3. ESC + switch the LED light in the upper right corner
4 ESC + the third from the bottom right (the third from the top): modify Flowing water light effect
5. ESC + second from bottom right corner (4th from the top): modify the water light effect
Description:
1.
Modify the USB display device name in usb_desc.c. This function is changed to
const uint8_t Joystick_StringProduct[JOYSTICK_SIZ_STRING_PRODUCT] =
2. Change the number of lights to the array below. It is recommended to give more space under
uint16_t PixelBuffer2[1024] = {0};// led * 24 +20 under ws2811.c
3.
WS_SetAll(WsDat1,25);
LED_SPI_Update(WsDat1,25,2); //Light array, number of lights, PB15 corresponds to SPI2, the
first is the function of running water light assignment array, the
second is the output To the lamp, so you can update the second by directly outputting the second after changing the array
The default state is the running light:
ESC +-to switch lighting effects
ESC + PGDN key to switch to the switch water lamp mode
ESC + 9 (.> the above 9) and ESC+.> that key can adjust the color effect of the water lamp
Bottom of the board
The Bluetooth HID module is soldered in the air
PCB steel plate (the ones without money can only be used for PCB wood)
