Its ARM Cortex-M3 core runs at 72 MHz, giving makers and students far more headroom than a classic 8-bit board while staying small enough for embedded builds. It suits anyone moving from an Arduino Uno to faster, peripheral-rich projects.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eMCU: STM32F103C8T6, ARM Cortex-M3 at 72 MHz\u003c\/li\u003e\n  \u003cli\u003eMemory: 64 KB Flash, 20 KB SRAM\u003c\/li\u003e\n  \u003cli\u003eLogic level: 3.3V (several GPIO pins are 5V tolerant)\u003c\/li\u003e\n  \u003cli\u003eI\/O: up to 37 GPIO, 12-bit ADC, multiple hardware timers\u003c\/li\u003e\n  \u003cli\u003eInterfaces: 2x SPI, 2x I2C, 3x USART, USB 2.0 full-speed (micro-USB)\u003c\/li\u003e\n  \u003cli\u003eDimensions: approx. 53 x 22 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eCompatible with\u003c\/h2\u003e\n\u003cp\u003eProgram it through the Arduino IDE with the STM32duino core, PlatformIO, or STM32CubeIDE.
