Atmel AVR ATmega328 microcontroller module with USB UART.

Crumb328 V2.2 AVR ATmega Module

Description

Crumb328 V2.3 is a versatile and very compact/small (just 35x18mm size!) microcontroller module with the ATmega328P microcontroller and CP2102 USB UART converter. All microcontroller signals are available on pin headers. A selectable XTAL crystal is included.

The module is shipped without preassembled pin 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.
