Description :

The SparkFun 1-Channel LoRa Gateway is a powerful device that can handle 3 networks (915MHz LoRa, Bluetooth, and WiFi)
The device can convert LoRa radio messages into data packets that can be accessed via the web
It's a low-cost tool for monitoring a dozen-or-so LoRa devices and relaying their messages to the cloud
The device comes with a Qwiic connector and a breadboard-compatible array of ESP32 pin-breakouts
It can act as a gateway or a device, but not both at the same time
To ensure proper setup, it's recommended to have another LoRa device or gateway to transmit/listen to
To use the 915MHz radio on the gateway, an antenna is required (two options: 3-inch solid-core wire or 915MHz antenna with a U.FL connector)
