Atmel AVR ATmega2560 microcontroller module with USB UART, RS232 and RS485.

Crumb2560 V1.1 AVR ATmega Module

Description:

Crumb2560 V1.1 is a versatile and very compact/small (just 61x30mm size!) microcontroller module with the ATmega2560 microcontroller, CP2102 USB UART converter, RS232 and RS485 transceiver. 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.
