STM32 GPIO Output Configuration and Control Techniques
General Purpose Input/Output (GPIO) pins typically operate with in a logic voltage range of 0 to 3.3V. While certain inputs may tolerate 5V, output stages are strictly limited to the 3.3V supply. To control higher-power devices such as motors or relays, an external driver circuit must be integrated between the MCU pin and the load.

STM32 USART Serial Communication Protocol
Communication Interfaces
Communication interfaces enable data transfer between devices to expand hardware systems. Communication protocols define rules for data exchange between devices.
Common communication interfaces include:
USART: TX (transmit) and RX (receive) pins
I2C: SCL (serial clock) and SDA (serial data)
SPI: SCLK (serial clock), MO ...
