CS32 | Blue Pill | 72MHz | 64KB | STM32 clone

The CS32 STM32 clone, also known as the Blue Pill, is an extra powerful small Arduino, a bit larger than the Arduino Nano but with better performance and more storage. Easily programmable via the Arduino IDE.

NOTE: NOT SUITABLE FOR BEGINNERS

The Blue Pill comes standard only with UART firmware that belongs to the chip. With this, you can upload a sketch or bootloader using a serial adapter such as the FT232RL on the TX (A9) and RX (A10) pins. If you also want to work via USB, you first need to install the stm32duino bootloader. See the Arduino_stm32 project’s GitHub for further details.

Clock speed 72Mhz and 64KB memory.

Model: STM32F103C8T6.
Processor: ARM 32 Cortex-M3 CPU.
Frequency: 72 MHz
Memory: 64K flash memory, 20K SRAM.
2.0-3.6 v, I/O.
27 GPIOs
10x 12-bit Analog Digital Converter
USART/ I2C/ SPI/ USB/ CAN/ DMA
