Product introduction
What’s this?
WiFi LoRa 32 is a classic IoT development board widely used in many open-source projects and IoT products.
Main Features
The HT1303 LoRaWAN concentrator is a mini-PCIe-based LPWAN module built around the Semtech SX1303 chipset, designed for seamless integration into routers or other network equipment with LPWAN Gateway capabilities. It is compatible with any embedded platform that includes a free mini-PCIe slot with SPI/USB connectivity. When paired with appropriate driver hardware and a Linux operating system—such as on a Raspberry Pi—it can function effectively as a LoRa gateway.
