ESP32 LoRa 1-Channel Gateway LoRa 單通道 LoRaWAN 網關模組 SparkFun 原裝進口

ESP32 LoRa 1-Channel Gateway LoRa 單通道 LoRaWAN 網關模組 將 ESP32(一種具有WiFi和藍牙無線電的可編程微控制器)與RFM95W LoRa收發器相結合,創建了單通道LoRa網關。它是一種完美的,低成本的工具,用於監控十幾個LoRa設備,並將其消息中繼到雲端。

ESP32 LoRa 1-Channel Gateway LoRa 單通道 LoRaWAN 網關模組  配有 Qwiic連接器 和麵包板兼容的 ESP32 引腳分支陣列,還可用作通用ESP32 / RFM95W開發平台。因此,您可以將其轉換為LoRa設備,並使用功能強大的ESP32微控制器來監控傳感器,託管 Web 服務器,運行顯示器等,而不是將其用作LoRaWAN網關。這些板是開始進入 LoRa和 LoRaWAN 世界的好方法。 ESP32 LoRa 1-Channel Gateway LoRa 單通道 LoRaWAN 網關模組 不僅可以編程為通用的單通道網關,而且還可以用作LoRa設備或通用ESP32 / RFM95W 開發板。

ESP32 LoRa 1-CH Gateway, LoRaWAN, and the Things Network

The ESP32 LoRa 1-CH Gateway combines an ESP32 – a programmable microcontroller featuring both WiFi and Bluetooth radios – with an RFM95W LoRa transceiver to create a single-channel LoRa gateway. It’s a perfect, low-cost tool for monitoring a dozen-or-so LoRa devices, and relaying their messages up to the cloud.

Complete with a Qwiic connector and a breadboard-compatible array of ESP32 pin-breakouts, this board can can also serve as a general-purpose ESP32/RFM95W development platform. So, instead of using it as a LoRaWAN gateway, you can turn it into a LoRa device, and use the powerful ESP32 microcontroller to monitor sensors, host a web server, run a display or more.

These boards are a great way to begin dipping your toes into the world of LoRa and LoRaWAN. Not only can they be programmed as versatile single-channel gateway, but they can also be used as a LoRa device, or a general ESP32/RFM95W development board.

For more information, check out our ESP32 LoRa 1-CH Gateway, LoRaWAN, and the Things Network tutorial, which explains how to set the board up, and get it connected to The Things Network.
