The STM32F103R6T6A is a low density performance line STM32 F1 series 32-bit Microcontroller incorporates the high-performance ARM Cortex-M3 RISC core operating at a 72MHz frequency, high speed embedded memories (Flash memory up to 32kB and SRAM up to 10KB) and an extensive range of enhanced peripherals and I/Os connected to two APB buses. This device offer two 12-bit ADCs, three general purpose 16-bit timers plus one PWM timer, as well as standard communication interfaces - up to one I²C, one SPI, two USARTs, an USB and a CAN.
