PURPOSE

Adapt the odd pad pitch of the RFM69CW or RFM69HCW to a breadboard friendly spacing and lay the pins out so that they match with the ATMega 328p-DIP ideally.

SIZE & COST

18.64mm x 21.16mm = $1.02 per board

DISCUSSION

An extremely small breakout board for adapting the odd pad pitch of the RFM69CW radio to breadboard friendly pin spacing. In particular some care was taken to place pins such that they work perfectly with an ATMega 328p-DIP (the chip in Arduinos). Used in this way, the board should span pins 15 through 22 on the 328p so as to match up MISO, MOSI, SS, SCK, VCC, and GND. The only other pin needed in some cirumstances is DIO0 which is mated up to PB1.
