STM32 Blue Pill
- 32-bit ARM Cortex-M3 processor, 72MHz.
- 64KB Flash and 20KB SRAM.
Description
The STM32F103C8T6 Blue Pill is a compact development board powered by a 32-bit ARM Cortex-M3 microcontroller running at up to 72MHz. It offers 64KB Flash memory, 20KB SRAM, and up to 37 GPIO pins for connecting sensors, displays, motors, and other electronic components. The board includes multiple communication interfaces, including UART, SPI, I2C, CAN, and USB support. Its 12-bit ADC channels allow analog sensor measurements, while timers and PWM outputs support motor and actuator control. It can be programmed using STM32CubeIDE, Keil, PlatformIO, or Arduino IDE with the appropriate STM32 core. SWD and JTAG interfaces support debugging and programming. Its compact design makes it suitable for robotics, automation, embedded systems, and electronics learning projects. The board uses 3.3V logic, so check voltage compatibility before connecting peripherals.
