NRF24L01-based remote control

Communication: NRF24L01
Main controller: STM32F4
TYPE-C: serial port, 5V power supply and lithium battery charging
power supply is 3.7V lithium battery, boosted from 5V to 3V,
one SWD programming interface,
four joystick channels (two joysticks XY),
two dial channels,
fourteen button channels,
one power acquisition channel and one buzzer channel.
The screen uses a 4.0-inch TFT color screen (SPI integrated), with or without touch, both are compatible.
Note: When selecting a screen, make sure the pins match. Joysticks and buttons need to be externally connected. You can directly use wires and then insert them with terminals, or you can draw a small channel board, solder the peripherals on it and then connect them to the main controller through terminals. In my practical experience, I have tried both methods. Wires are more flexible for the shape design, but there is a probability of wire breakage; the channel board is stable but will limit the shape of the remote control.
