[Wizza]

Nice work Wizza!

I take the opportunity to write a little note, specially for those that chose to use the BME280 sensor (not the BMP280).

As the BME280 will also act as your inside Temperature / Humidity sensor, I think its better install it outside of the Pro2 PLUS box, and connect it to the RX board using some wires.

Werk raises a very good point above.  The pictured BME module and header socket on the PCB board in the photos above (Pro2+ assembly) is ok for testing and setup, however once you put your finished RX board into a case/enclosure, you will probably want to move the BME sensor to outside of the enclosure for best environment sensing/readings.

In the past I have used these little black plastic enclosures with great success.  Below is the URL to the cases that I bought on eBay, and I'll be sure to report back and show some more photos once I get to the case build stage.

Below is a photo of my last receiver station showing the temp module mounted on the rear in one of these enclosures.
