Description

Lora Node with integrated PCB-Antenna 868MHz for WaziUp and LowCostLoRaGw https://github.com/CongducPham/LowCostLoRaGw. Thanks to: https://github.com/cernohorsky/LoRa-Node !

I added a connection for a DS18B20, a LED and a serial GPS-Module.

Burn fuses like this, that the Atmega is working down 2.8V: https://forum.mysensors.org/topic/7296/how-to-burn-fuses-so-that-pro-mini-3-3v-would-go-down-to-1-8v-solved/9

I ordered assembled PCB's at JLC-PCB.
