Build a Professional Transmitter With STM32 + nRF24L01 PART-2

Подробнее о видео

In this video, we build a powerful and professional-grade RC transmitter using the STM32F103C8T6 (Blue Pill) microcontroller, nRF24L01+ wireless module, and a 0.96" OLED display via I2C. This transmitter is perfect for controlling RC cars, drones, or robots with precise analog input and real-time feedback.

📡 Key Features:

STM32 + HAL-based configuration (no Arduino)

Analog joystick/potentiometer input via ADC

Wireless data transmission over 2.4GHz with nRF24L01+

Live control data displayed on OLED (I2C)

50Hz loop for smooth control signals

🧰 Hardware Used:

STM32F103C8T6 (Blue Pill)

nRF24L01+ 2.4GHz RF Module

0.96" OLED Display (SSD1306, I2C)

Analog Joysticks or Potentiometers

CP2102 USB to TTL Programmer

3.3V LDO Regulator (recommended)
