STM32F103REY6TR

STM32F103REY6TR is STMicroelectronics’ MCU from the STM32F1 family, based on a 32‑bit ARM Cortex‑M3 core. It runs up to about 72 MHz and integrates on‑chip flash and RAM, plus a rich set of peripherals (USART/UART, SPI, I2C, CAN; ADCs; multiple timers; DMA; RTC; and USB FS on many F1 variants). It operates from 2.0 to 3.6 V. The REY6TR suffix indicates a specific device variant and packaging (check the datasheet for exact details). It is well supported by ST tooling (CubeMX/CubeIDE, HAL/LL drivers) and suitable for general‑purpose embedded, motor control, and sensing tasks. For exact memory sizes, pinout, and peripheral counts, refer to the STM32F103REY6TR datasheet and reference manual.
