Crumb2560 V1.1 is a versatile, small (just 60×30mm footprint!) microcontroller module with the ATmega2560 microcontroller, a CP2102 USB UART converter, a MAX3221 RS232 transceiver and a 75ALS176 RS485 transceiver. All ATmega2560 signals are available on pads. A watch crystal (TOSC) is preassembled and a selectable XTAL crystal is included.
The Crumb2560 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.
