The RFM95W handles the 915MHz band while the ESP32 takes care of Bluetooth and WiFi capabilities. One of the ideal uses is to convert LoRa (Long Range) radio messages into data packets that you can access via the web, but of course, the flexibility it offers can be put to many more uses! It's a perfect, low-cost tool for monitoring a dozen-or-so LoRa devices and relaying its messages up to the cloud.\u003c\/p\u003e \u003cp\u003eComplete with a Qwiic connector and a breadboard-compatible array of ESP32 pin-breakouts, the Gateway can also serve as a general-purpose ESP32\/RFM95W development platform. The LoRa Gateway can act as either a gateway (hence the name) or a device, but not both at the same time. To really be sure that your setup works as expected you should have another LoRa device to listen to, and\/or another LoRa gateway to transmit to. The good news is that the LoRa Gateway 1-Channel can act as both so if you have two then you’re all set.\u003c\/p\u003e \u003cp\u003eTo use the 915MHz radio on the gateway you will need an antenna - for which you have two choices. You may cut a length of solid-core wire to approximately three inches for a through-hole antenna connection with strain relief or you can use a 915MHz antenna with a U.FL connector for higher performance antennas.\u003c\/p\u003e \u003cdiv class=\"center-block text-center\"\u003eGet Started With the SparkFun LoRa Gateway Guide\u003c\/div\u003e \u003c\/div\u003e \u003c\/div\u003e \u003ch2\u003eFeatures\u003c\/h2\u003e \u003cdiv role=\"tabpanel\" class=\"tab-pane fade\" id=\"features-tab\"\u003e \u003cdiv class=\"col-sm-12\"\u003e \u003cp\u003e\u003cem\u003eNew For this revision: Update the ESP32-WROOM-32 module from 4MB to 16MB\u003c\/em\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eESP32-WROOM-32 module - 16MB \u003cul\u003e \u003cli\u003eWiFi, BT+BLE microcontroller\u003c\/li\u003e \u003cli\u003eIntegrated PCB antenna\u003c\/li\u003e \u003c\/ul\u003e \u003c\/li\u003e \u003cli\u003eHope RFM95W LoRa modem \u003cul\u003e \u003cli\u003eFrequency range: 868\/915 MHz\u003c\/li\u003e \u003cli\u003eSpread factor: 6-12\u003c\/li\u003e \u003cli\u003eSPI control interface\u003c\/li\u003e \u003c\/ul\u003e \u003c\/li\u003e \u003cli\u003eU.FL antenna connector for LoRa radio\u003c\/li\u003e \u003cli\u003eReset and ESP32 pin0 buttons\u003c\/li\u003e \u003cli\u003e14 GPIO ESP32 pin-breakouts\u003c\/li\u003e \u003cli\u003ePower and user LEDs\u003c\/li\u003e \u003cli\u003eQwiic connector\u003c\/li\u003e \u003cli\u003eCH340C USB-to-Serial interface\u003c\/li\u003e \u003cli\u003eMicro-B USB connector for power and programming \u003cul\u003e \u003cli\u003eAll current consumption tested at 5V\u003c\/li\u003e \u003cli\u003e~170 mA when formatting SPIFFS in Gateway mode\u003c\/li\u003e \u003cli\u003e~150 mA when searching for WiFi network in Gateway mode\u003c\/li\u003e \u003cli\u003e80 to 100 mA in steady operation of Gateway\u003c\/li\u003e \u003cli\u003e~70 mA when using the LoRa Device example\u003c\/li\u003e \u003c\/ul\u003e \u003c\/li\u003e \u003c\/ul\u003e \u003c\/div\u003e \u003c\/div\u003e \u003ch2\u003eDocuments\u003c\/h2\u003e \u003cdiv role=\"tabpanel\" class=\"tab-pane fade\" id=\"documents-tab\"\u003e \u003cdiv class=\"col-sm-12\"\u003e \u003cul\u003e \u003cli\u003eSchematic\u003c\/li\u003e \u003cli\u003eEagle Files\u003c\/li\u003e \u003cli\u003eHookup Guide\u003c\/li\u003e \u003cli\u003eDatasheets \u003cul\u003e \u003cli\u003eESP32 WROOM\u003c\/li\u003e \u003cli\u003eRFM95W\u003c\/li\u003e \u003c\/ul\u003e \u003c\/li\u003e \u003cli\u003eArduino Firmware\u003c\/li\u003e \u003cli\u003eArduino Library\u003c\/li\u003e \u003cli\u003eGitHub\u003c\/li\u003e \u003c\/ul\u003e \u003c\/div\u003e \u003c\/div\u003e","brand":"Sparkfun","offers":[{"title":"Default Title","offer_id":49567742230755,"sku":"xpu1787258358796","price":30.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0734\/2961\/4819\/files\/sparkfun-lora-gateway---1-channel-esp32-discontinued_1.jpg?v=1787258363"}],"url":"https:\/\/dewverna.com\/collections\/wireless.oembed","provider":"Dewverna","version":"1.0","type":"link"}
