Cordi stm32f100 EADOGM-132 Prototyping Board

We often need a controller for interfacing our electronic prototype circuit.

For almost all of our circuits on a breadboard we need a

• Controller
• Power stabilization
• Communication interface (RS232)
• Digital TTL-I/O, sometimes SPI, timers or other controller functions
• DAC and ADC
• Maybe a display, maybe with backlight
• RTC

It's always the same...

Short: A small real embedded system for rapid prototyping.

Existing prototyping boards are mostly stand alone boards, providing as many as possible of the controller's peripherals with all additional hardware circuits to demonstrate the capabilities of the controller. Embedding these boards is not easy and can only be done with fragile mechanical and cable constructions and some power supply artworks.

Most times we don't need all this stuff, but only a small reasonable board, with some standard features easy to connect, so we decided to roll our own bread board compatible system to embed.
