Hi,
looks very interesting.

Please give a more elaborate description here on the forum, including library and/or sw interface links datasheets etc. In the end your customers mixing the whisker with Arduino will probably end up here .. Make it a win win ;)

Thank you.

The claims for this device (4-10 mile range and 5 year battery life for AA batteries, with 100 mW transmit power) seem ridiculous. I suspect there will be some very disappointed backers.

"LoRa" a trademark of HopeRF. Interested experimenters can already buy Arduino-compatible modules here http://www.anarduino.com/?cid=24 and test these claims for themselves (note, I have no connection with anarduino.com).

A word of warning. The experience is likely to be frustrating. See the comments and trial Arduino code here https://github.com/anthonywebb/RFM92

No way you would get that range with the omni antenna shown, but if you used something highly directional (scrap Dish Network dishes?) on both ends it's certainly doable.  The 5 year life in my mind would be attainable only with very intermittent data bursts, certainly nothing seeing continuous use.
