also available from TinyTronics. I just picked up some stuff in EIndhoven today: “Yes - LoRa is becoming a big hit - I am also looking at some LoRa modules to sell.” :slight_smile:

I previously bought a lot of stuff directly from China, but after having some problems with faulty stuff, I now buy most of my stuff from this shop.
