R100/R101 are placeholders for a reset button (connecting the AVR reset pin with ground) or a connection with the IEC reset line (AVR reset pin connected via a standard diode with IEC reset – the cathode of the diode has to point towards the IEC reset line). This is optional.
Some notes as of June 2013
The SD card slot used in this design is out of production. Until somebody provides an updated layout, an easy workaround is using MicroSD cards and soldering a MicroSD to SD adapter to the board.
Newer firmwares support the ATmega1284P. You should use that instead of the ATmega644.
