Plugin Breadboard Modules with Atmel/Microchip Microcontrollers and various interfaces.

Sammy SAM/SmartARM and Crumb AVR ATmega and Xmega microcontroller modules offer a high-density integration at a tiny form factor. Based on various Atmel AVR microcontrollers, they further provide peripherals like RS232, RS485, CAN bus, USB UART converter, USB controller, Ethernet, etc. All relevant microcontroller and peripheral signals are available on pin headers in standard 2.54mm (0.1 inch), thus providing easy integration of Crumb modules onto breadboards or wirewrap boards.
