I loaded the RFM69 node sketch with SWITCHIRQ enabled with a RF69_915MHZ radio (IS_RFM69HW disabled). It came on right away with no issues. This weekend, I'll build out a little door monitor case and test with a simple reed switch powered by a CR2032 battery. Initial though are encouraging. Initially, two changes I would like to see are:
the width of the board to be a bit wider to all for breadboard prototyping and PCB installation. However, I should move past this as a PCB will increase the footprint of an already small size.

Here are some photos with the button nodes along side a Pro Mini
papa: Thanks for an encourage update on this product, Joshua. Keep it coming.
There is another, cheaper, board and radio here Anarduino and it appears that the radio is wired in the same as ours as well.
Papa: Yes, the Anarduino Miniwireless is a small board that can include an RFM69 radio, extra memory (helps for over the air programming), & a real time clock. It can work well for much of our node projects. I've written some threads documenting them including over the air programming & a mail box node. One needs to use something like an FTDI board to program it at least the first time.
