WM1302 Pi Hat for Raspberry Pi

Image
Product Introduction: ​ WM1302 Pi HAT is an add-on expansion board designed specifically for attaching the WM1302 LoRaWAN Gateway module based on SX1302 to Raspberry Pi versions up to Raspberry Pi 4B. It also integrates the LoRaWAN authentication chip and GPS module. WM1302 module is a new generation of LoRaWAN gateway module with mini-PCIe form-factor. Based on the Semtech® SX1302 baseband LoRaWAN® chip, WM1302 unlocks the greater potential capacity of long-range wireless transmission for gateway products. It features higher sensitivity, less power consumption, and lower operating temperature than the previous SX1301 and SX1308 LoRa® chip. WM1302 Pi HAT supports the WM1302 module's mini-PCIe form-factor and can automatically configure the standard 52-pin golden fingers to the Raspberry Pi GPIO connector with a 40-pin compatible header. This simplifies the development process for users to integrate with Raspberry Pi. WM1302 Pi HAT works as an extension board and helps add the func
