Reply To: Ra-02 (SX1278) module driven from a 5V Nano, it heats up and won't join

I asked around, and the gateway is 868. I got an RFM95W 868 and a 3.3V Pro Mini, and selected CFG_eu868. I had also typed the DevEUI backwards, and after correcting it the second attempt gave EV_JOINED, and the join shows up in the frames log. The old Ra-02 has probably really burned out too, it doesn’t respond at all anymore 😅
