Small is Beautiful: Minimod18
A new microcontroller board for Elektor ATmega projects
Published in issue 400, April 2010
Minimod18 is a very compact general-purpose microcontroller module. It includes frequently required peripheral components, such as pushbuttons and an LC display, as well as several interfaces (USB, I²C and ISP/SPI). You only have to assemble the peripheral circuitry necessary for your specific application and connect it to the Minimod18. This way you can build a complete device with entry and display capability in almost no time.
