Overview

Verified for use

A lithium battery is used to step down the voltage to 3.3V through a low voltage dropout LDO to power the entire system. The Bluetooth module can only be powered by 3.3V, and the Bluetooth module does not need to be connected.

The entire system is developed based on CUBEMX

The wiring of each module is as follows:

joystick module
5 pins
3.3v power supply
GND
VRX ->PA4
VRY ->PA3
SW ->PA5

NRF24L01 module
8 pins
3.3V power supply
GND
IRQ ->PB10
CE ->PB11
CS ->PB12
SCK ->PB13
MISO->PB14
MOSI->PB15

OLED0.96 inch
SCL ->PB6
SDA->PB7

hc05 Bluetooth module
RX->PA9
TX->PA10
