Metaboard is a USB based prototyping board for Atmel's AVR microcontrollers. It is designed to be (mostly) compatible with [http://www.arduino.cc/ Arduino]. ~~It's~~ entire design (hardware and firmware) is Open Source.

= Design ~~Gloals~~ =

= Design Goals =

* Low complexity and thus extremely low price.

* Single sided PCB so that the board can be manufactured at home. If professionally manufactured, a single sided board is still cheaper.

* No SMD components. Easy to ~~assembler~~ at home.

* No SMD components. Easy to assemble at home.

* (Mostly) compatible with [http://www.arduino.cc/ Arduino] in board dimension and connector layout. Can also be programmed by Arduino's development environment via USB.

* No upfront investment for development environment or programmer hardware.

The most recent version of Metaboard can always be obtained via SVN from https://whatever.metalab.at/user/cs/metaboard/trunk.

A read-made package with PNG images for board schematics, layout and component side can be downloaded here.

= Firmware =

Metaboard is best used with [http://www.obdev.at/products/avrusb/usbasploader.html USBaspLoader]. This is a boot loader which emulates USBasp, a USB based AVR programmer. The main firmware loaded with this boot loader is your business, of course.

= Development Resources =

Zeile 38:

Example projects based on GCC can be found at http://www.obdev.at/avrusb/. Since these examples have not been developed for Metaboard, they must be modified with Metaboard's pin assignments and clock rate.

All resources related to Arduino can be found at http://www.arduino.cc/.

All resources related to Arduino can be found at http://www.arduino.cc/. If you want to use the USB port from within the Arduino development environment, see the following project log: http://code.rancidbacon.com/ProjectLogArduinoUSB.

Since Arduino insists on having a serial line to upload the firmware (although none is needed for usbasp), you may have to edit Arduino's preferences.txt file manually and set the variable serial.port to an existing device. Preferences.txt is in ~/Library/Arduino on the Mac.
