• Main control: Arduino Pro Micro, supports USB CDC, convenient for host computer programming (even WebUSB)

The computer sets the NRF frequency point, coordinates and preset colors that can be switched by buttons. When the USB is inserted, it will automatically synchronize to the MCU. When there are a large number of devices, just insert them one by one.

Why not use atmega32u4 directly? Because it is impossible to solder chips, so I can only use it by plugging in a micro.

• Wireless module: NRF24L01

Broadcast mode, only uses one frequency point, and the receiving end filters data that does not belong to itself through coordinates

Why not use the NRF24L01 chip directly? It is impossible to solder the chip (interrupting the repeater)

• Two switches and one button

Power switch and wireless module switch. When wireless is turned off, the preset color can be switched by pressing the button.

Turn off wireless and continue using it alone

• Lithium battery charging management module

TP4056 charges, ME2108 boosts 5V for arduino and LED use, ASM1117 steps down for NRF24L01 use

• About the host computer

It should be implemented using web pages + WebUSBSerial. It is planned to have functions such as setting preset colors and frequency points, setting coordinate matrices to switch colors wirelessly (do this after doing it, create a new folder)
