Crumb128-light AVR ATmega Module

Crumb128-light - Atmel AVR ATmega128 microcontroller module.


Crumb128-light is a versatile and very compact/small (just 40x30mm size!) microcontroller module with the ATmega128 microcontroller. All microcontroller signals are available on pin headers. A selectable XTAL crystal is included.

The module is shipped without preassembled pinn headers, since everybody has different preferences or requirements. A Connector Kit with a suitable set of pin headers and receptacles can be ordered optionally.

You can find further information in the Infosheet.
