I found this while googling for EU halow radios, This is the first i have seen selling EU 868 radios.

great to hear there are some EU devices.

but i guess real world EU datarates should be very low due to tiny bandwidth and duty-cycle regulations?!

I don’t think it’s worth it to try making it work for EU, the regulations make it all but useless.

I just bought the US 915MHz version of that hardware (or a direct clone - form factor is identical). Brief testing shows promise out to about 1/4 mile with 720p rtsp video (over the ground, not airborne). I intend to use the new Ethernet features for telemetry as well.

The modules take 5V power, and I cut apart the wall wart to accept USB 5V for testing outdoors on a laptop. It’s very low current draw.

It’s worth saying that the EU compliant versions supposedly only support about 5Mbps, where US ones are about triple that. Still, 5Mbps is plenty for MAVLink or low res video.

Im planning on going at glacial speeds, 1fps would be more than enough for me.
