CS32 | Blue Pill | 72Mhz | 64KB | STM32 clone (OT106-B65)

The CS32 STM32 clone, also called Blue Pill, is an extra powerful small Arduino, a bit bigger than the Arduino Nano but with better performance and more storage. Simply programmable via the Arduino IDE. NOTE: NOT SUITABLE FOR BEGINNERS The Blue Pill only comes standard with UART firmware that belongs to the chip. This allows you to upload a sketch or bootloader with a serial adapter such as the FT232RL on the TX (A9) and RX (A10) pins. If you also want to be able to work via USB, first put the stm32duino bootloader on it. See also the github of the Arduino_stm32 project for the details.Clock speed 72Mhz and 64KB memory.Model: STM32F103C8T6.Processor: ARM 32 Cortex-M3 CPU.Frequency: 72 MHzMemory: 64K flash memory, 20K SRAM.2.0-3.6 v, I/O.27 GPIO’s10x 12-bit Analog Digital ConverterUSART/ I2C/ SPI/ USB/ CAN/ DMAOperating voltage: 3.3/5VReset (POR/PDR).4-16 MHz crystal.On-board Mini USB interface, for power supply and USB communication with Arduino IDESize: 5.3 cm x 2.2 cm.Note: On the Blue Pill boards the 5V pin is connected directly to the 5V of the USB port, without a protection diode. So do not use the USB port at the same time as an external power supply.DimensionsLength: 5.4cmWidth: 2.3cmHeight: 1.1cm
