KAmod BluePill+ - Development board with STM32F103C8T6 microcontroller, compatible with WeAct BluePill

Description

The Kamod BluePill+ evaluation board is a modern version of the popular BluePill platform, featuring the STM32F103 microcontroller. It offers numerous design and functional improvements that make it more reliable and versatile. The new PCB design enhances power stability, and built-in ESD protection safeguards against damage from electrostatic discharges. The board is equipped with a USB-C connector, which serves as both a power supply and an interface for programming and USB communication. With the pre-installed bootloader, the Kamod BluePill+ can be easily programmed using popular tools like Arduino IDE or STM32CubeIDE without the need for an external programmer, such as ST-Link.

The STM32F103 microcontroller offers two ADC converters for precise analog measurements, as well as I2C and SPI interfaces for communication with external modules. The board includes Reset, BOOT, and KEY buttons, simplifying mode switching and microcontroller resetting. There is also the option to solder an SPI Flash memory, such as W25xxx, which expands the board's potential applications. This makes it an ideal tool for those developing ARM Cortex-based projects who are looking for a reliable, easy-to-use platform. The Kamod BluePill+ is suitable for various projects based on STM32 microcontrollers.
