Description

Crumb128 V4.0 is a versatile and very compact/small (just 40x30mm size!) microcontroller module with the ATmega128 microcontroller, CP2102 USB UART converter and RS485 transceiver. 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.
