We’ve seen plenty of ESP32 LoRa boards with the traditional 433 MHz, 868 MHz, or 915MHz frequencies, but I think LilyGO LoRa V1.8 (aka T3 V1.8) is the first ESP32 board that integrates a Semtech SX1280 transceiver for the 2.4GHz LoRa standard used for global coverage, notably maritime applications, and ranging.
The ESP32 & SX1280 board also offers 26 pins for expansion, a microSD card for data storage, a 2-pin connector for batteries, a 0.96-inch OLED for information display, and comes with a 3D antenna and u.FL connector for WiFi and Bluetooth, and an SMA antenna for LoRa connectivity.
LilyGO LoRa/T3 V1.8 specifications:
LilyGO provides some Arduino sketches for 2.4GHz LoRa including a ranging (ToF) demo, as well as receive and transmit samples on Github.
LilyGO LoRa V1.8 board sells for $27.18 plus shipping on Aliexpress, and ships with a 2.4GHz antenna, two headers, and a cable to connect a battery. If you don’t own a 2.4GHz LoRaWAN gateway, you’ll need two to experiment with P2P connection for ranging and/or data transmission.
