It looked so good, but it was too good to be true. he has installed the RFM96W and not the RFM95W. on the one hand that means 13 instead of 20 dbi output, but more importantly no lora modulation!
But the solution with the MCP16251 step-up switching regulator is great and I will take on my node. such a board for lora, just for this price would of course top!
