STM8S103F3 P6 Development Board

This development/breakout board (HCDVBD0034) is based around the ST Microelectronics S103F3P6 microcontroller. STM8 microcontrollers are an ultra low cost solution to embedded control. This development board provides convenient access to the devices I/O pins via standard 2.54mm pitch headers (require soldering). Besides providing access to most of the microcontrollers I/O, there is additionally a microUSB connector for powering from a USB port, and a standard ST SWIM programming/emulation header that allows for programming or debugging using a compatible programmer such as our low cost ST-Link compatible USB programmer (HCDVBD0016). An on-board 3.3V regulator provides power to the board supplied via the 5V USB or 5V header pins. The ST tool chain (STVD) is available as a free download from the ST website and is fully compatible with this board. There are also additional third party tools such as the Cosmos ANSI C compiler (8K limited) and the SDCC (Small Device C Compiler) which can be downloaded for free. Links to these tools are provided at the bottom of this post.
