PEG v4.2 upgrade chips (PEG chips)

FOR UPGRADING AN OLD PEG (prior to 2012).
Since summer of 2012, all PEG kits ship with these chips (v4.2).
Since summer of 2015, all PEG modules (factory built) do not use replaceable chips

These chips fixes a minor bug that caused the ping time not to clear when the button is held down for 2 seconds. Also adds AR mode for Async triggers.
Instead of buying these chips, you can also download the hex file and burn it yourself using an AVR ISP programmer: Here
