For ease of development and as to make an EduBuzzer expandable to an EduBuzzer base station, a serial line is exposed for connection with an "FTDI cable" -- power supply, RX/TX, reset button. Thus, the devices can be flashed using a bootloader.

The design takes care to stay compatible with the Arduino even if not Arduino is used in the final version. Thus, prototypes can be built on Arduino shields as well (read the [[Building your own EduBuzzer#The main board|building documentation]] for details).

The PCBs are described as Eagle files in [[HSC2011/Download instructions|the project repository]] in the <tt>hardware</tt> directory in <tt>buzzer.{brd,sch}</tt>. It is routed on two sides and has three big holes for mounting inside the EduBuzzer.
For prototypes based on an Arduino, a reduced wiring scheme is described in <tt>hardware/arduino_schield.sch</tt>, which can be reproduced on an Arduino prototyping shield or a custom shield described in <tt>hardware/arduino_schield.brd</tt>. Those devices won't fit in the cases, apart from that, are fully usable as well.
For further information, read the [[HSC2011/Building your own EduBuzzer#The main board|building documentation]].

This describes all the electronic parts required for completing the buzzer shield. Parts not needed in combination with an Arduino have their count as the second one in the Amount column. The Bauteilsortiment column refers to where you can find them [[Bauteilsortiment|in the metalab's parts repository]].
