Crumb128 V4.0 is a versatile, very small (just 40x30mm footprint!) microcontroller module with the ATmega128 or AT90CAN128 with CAN transceiver or ATmega2561 microcontroller, a CP2102 USB UART converter and a RS485 transceiver. All MCU signals are available on pads. A watch crystal (TOSC) is preassembled and a selectable XTAL crystal is included.
The Crumb128 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.
