Microcontroller Module with ATmega644P, USB, RS485.

Crumb644 V1.0 is a versatile, very small (just 51x18mm footprint!) microcontroller module with the ATmega644P microcontroller, a CP2102 USB UART converter and a 75ALS176 RS485 transceiver. All ATmega644P signals are available on pads. A selectable XTAL crystal is included.

The Crumb644 is being shipped without preassembled pinheaders, since everybody has different preferences here. A suitable Connector Kit with pin headers and receptacles can be ordered optionally.

Further information can be found in the infosheet.
