This 1-Channel Lora Gateway from SparkFun provides a robust 3-network capable board by combining a ESP32 WROOM module and an RFM95W LoRa modem. The RFM95W takes care of the 915MHz band while the ESP32 handles both the Bluetooth and WiFi functionality. This Lora Gateway is perfect for converting Long Range (LoRa) radio messages into data packets which can be accessed via the internet. However it can be used for so much more due to the adaptability of the device! In Short, this is a great entry level module for monitoring several LoRa devices and sending their data packets up into the cloud.

In-line with the rest of SparkFun’s Qwiic-enabled products, the LoRa Gateway comes complete with a Qwiic connector so you can “qwiicly” hook it up to the rest of your Qwiic devices! A breadboard compatible array of ESP32 pin-breakouts helps those who haven’t got onboard with the former. This Lora Gateway can even be used as a general-purpose ESP32/RFM95W development platform, with the option of running as either a Gateway or a device but not both in unison. To make sure that your setup works as expected you should have another LoRa device to listen to, and/or another LoRa gateway to transmit to. Good news is that the LoRa Gateway 1-Channel can act as both so if you have two then you’re all set.

This Lora Gateway does not come with an antenna required to use the 915MHz radio. For a high performance antenna, we recommend using a 915MHZ with U.FL connector. If you want to go full DIY, You can cut a length of solid-core wire to approximately three inches for a through-hole antenna connection with strain relief!
