STM32F103CBT6 Development Board Maple Mini Compatible ARM Cortex-M3 Microcontroller

Product Description:
The STM32F103CBT6 Development Board is a compact and high-performance microcontroller board based on the ARM Cortex-M3 32-bit processor, fully compatible with the popular Maple Mini platform. Designed for developers looking for more power than an Arduino without sacrificing ease of use, it offers a seamless transition from the Arduino ecosystem through the Maple IDE or STM32duino (Arduino IDE support).

With a 72MHz CPU frequency, 120KB Flash memory, and 20KB SRAM, this board provides significantly higher speed and memory than standard 8-bit microcontrollers. It features 34 GPIO pins, 12-bit ADC, PWM outputs, and multiple communication interfaces such as SPI, I2C, and USART, making it ideal for robotics, data acquisition, motor control, and embedded projects.

Compact and power-efficient, the STM32F103CBT6 board delivers professional-grade performance in a small footprint, perfect for advanced embedded applications.
