Description

The STM32F103C8T6 Blue Pill provides a compact platform for learning and developing embedded applications. Its 32-bit Arm Cortex-M3 processor supports digital control, analog measurement and communication with compatible peripherals.

The MCU includes USART, SPI, I²C, USB and CAN controllers, along with timers and 12-bit analog-to-digital converters. Available connections depend on the board layout and pin configuration. CAN communication requires an external transceiver.

Typical Blue Pill boards include a USB connector, reset button, boot-selection jumpers and debugging connections. Confirm the connector type, fitted headers and supplied accessories against your actual stock.

Programming and debugging can use a compatible SWD programmer such as ST-LINK. USB uploading requires suitable firmware or a bootloader; do not advertise a preinstalled USB bootloader unless verified.
