Review on 🔧 DIYmall Assembled ESP32 OLED WiFi Lora Kit: 0.96inch OLED Display, Bluetooth-Compatible Development Board, Lora Transceiver - Ideal for Arduino ESP8266 NodeMCU by James Nielsen

Excellent quality and packaging! I've always heard that these LoRa radios can work over long distances like 10km, but I was skeptical about them. Now, after getting two of these from DIYmall, I can tell you firsthand that the distance isn't a myth. After setting up a code on both devices to talk to each other and on a fourth, I asked my friend to take one of them to my house 2 miles away and was shocked to see that they were actually paired to each other and talk to each other! I had code that allowed us to type each other in a serial terminal and we sent several messages back and forth. And that was done with the antenna that came with the device, you could only imagine how far you could get with a yagi antenna or something. I also used them via bluetooth to play with a toy robot that I could control with my phone. Get them and let yourself be surprised.
