High sensitivity: down to -148 dBm. From the datasheet. There probably needs to be some margin, but my experience with Sigfox shows that -130 is quite reliable. After that, packets start go missing. I would guess LoRa is similar.

@lafleur Great find, im tempted to test one out...

@doug Can't wait for you to release the BOM

@scalz I manage to narrow it down only to "drivers/ATSHA204" compile issues, which is signing.

@MiKa Hi. oki, in case i'll add some explanation.. I'll be busy for this week but you can simply use the serial gw example from MySensors for getting started, this should work. I didn't need to create a special board in arduino for this board, so if you're using it, you'll need to install&use the mattairtech SAMD21 board definition for the pin mapping. https://github.com/mattairtech/ArduinoCore-samd
