WIFI LoRa 32 V3 SX1262 868MHz with OLED

This is the latest version of the popular Heltec LoRa 32 V2 SX1276 module. The module retains the pin layout and functionalities of the V2 but now features USB-C and a better LoRa chip with the SX1262 instead of the SX1276. The handy board has an ESP32 with Bluetooth and WiFi connectivity, as well as a 128x64 OLED display. This way you have a great module for first experiments with LoRa. 

Before you can start, you need to check if there is a TTN (The Things Network) gateway nearby. You can find all TTN gateways on the following map:

Otherwise, you can of course also install a multi-channel gateway for the TTN yourself (The Things Network):
