Microcontroller module Chip45 CRUMB128-CAN

Crumb128 V4.0 is a versatile, very small (just 40×30mm footprint!) microcontroller module with the  AT90CAN128 with CAN transceiver, a CP2102 USB UART converter and a RS485 transceiver.

Detailed Description

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.
