Crumbuino-128 corresponds to our popular Crumb128 V4.0 module with the ATmega128 mikrocontroller and CP2102 USB UART converter. As Crumbuino-128 version the module comes with Arduino bootloader preloaded and mounted 16MHz crystal. Added is a set of suitable pin headers and receptacles (2x 32polig, 1x 8polig each + ISP header).

Due to the preloaded Arduino Bootloader and the integrated USB UART converter with mini-USB connector, the module can directly be used with the Arduino IDE as an e.g. Arduino Mega 2560 board.

Since the Arduino Software does not yet offer support for an ATmega128, we provide an extension to the Arduino Software. After installation you can select the Crumbuino-128 as target board and use it as usual.

You can find further information in the Infosheet.

Here you can download our extension to the Arduino Software: chip45-arduino-extension.zip, as well as a simple Arduino Sketch, for blinking the onboard LED: Blink_Crumbuino-128.zip.
