BluePill ARM STM32 STM32F103C8 Development Board

Product detailed description

It is a clone of microcontroller STM32F103 - CS32F103 CPUTAPID signature 0x2ba01477. For this reason, it will not be possible to use the original GDB debugger. The chip can be designated either CS32F103 or STM32F103.

The STM32F103xx microcontroller series includes a high-performance 32-bit ARM®Cortex®-M3 RISC core operating at up to 72 MHz, high-speed embedded memories (Flash memory up to 128 kB and SRAM up to 20 kB), a rich number of enhanced I/O ports and peripherals connected to two APB buses. The microcontrollers offer two 12-bit ADCs, three universal 16-bit timers plus one PWM timer, as well as standard and advanced communication interfaces: up to two I2C and SPI, three USART, USB and CAN.

These features make the STM32F103xx series of microcontrollers suitable for a wide range of applications such as motor drives, application control, medical and handheld devices, PC and gaming peripherals, GPS platforms, industrial applications, PLCs, inverters, printers, scanners, alarm systems, videophones, and more.

With its selection of specific components and compact dimensions, this development board is very suitable for beginners who are looking for a more powerful alternative to the Arduino Nano development board. Several development environments are available for this board, including Arduino an IDE. To program the board, you can use the ST-Link V2 programmer (or its clone) or the USART Bootloader.
