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

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…

After several attempts with other similar ESP32+LoRa development boards I encountered several problems: poor quality boards, some dead on arrival, missing or misleading documentation, failed attempts to implement LoRaWAN libraries, etc. This is the ESP32 development board exceeded my expectations (which were not very high initially). I got the latest (v2) version of the board, which I didn't expect. Since the connector's pins were already soldered on, I was able to get it working without any…

This board is a Haltech V2 LORA card. It comes with an unbalanced antenna that must be grounded. Unfortunately, in most applications no ground layer is available so antenna performance can be very good or probably very bad. Replacing the antenna with a dipole is best for most applications when size is not an issue. The rest of the board is of high quality. Disconnect the battery. The battery charges via a USB connection, and if it's going to be used in a fixed location and the battery is acting
