ATTNode v1

This is the first Iteration of the ATTNode PCB. Measuring only 36mmx47mm it is already quite small. The board features 6 free GPIO-Pins from the ATTiny84 + power on a 2.54mm pin header, a standard atmel-compatible programming header and solderpads for an optional onboard SMD LED + fitting current-limiting resistor. All further development will be on the next iterations of the board. See the navigation at the left for the newer versions. Firmware will stay compatible between different board versions as much as possible. Here are some pictures of the board:
