CrumbX128A3 V1.2 is a versatile, very small (just 40x30mm footprint!) microcontroller module with the ATxmega128A3 microcontroller, CP2102 USB UART converter, RS485 transceiver, voltage regulator and micro sd-card slot. All ATxmega128A3 signals are available on pads. A selectable XTAL crystal or watch crystal is included.
The CrumbX128A3 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.
