Need the bare LR1302 module? See the LR1302 LoRaWAN Gateway Module. For a standalone gateway, see the ThinkNode G1. The LR1302 LoRaWAN HAT is a powerful Raspberry Pi expansion board designed to enable seamless integration of SX1302-based LoRaWAN gateway functionality. It connects the LR1302 gateway module to Raspberry Pi boards (compatible up to Raspberry Pi 5), making it easy to build a compact and efficient LoRaWAN gateway solution. This HAT integrates a GPS module and RTC (Real-Time Clock), enhancing both positioning accuracy and time synchronization-critical for reliable LoRaWAN communication. It supports a mini-PCIe interface for the LR1302 module and automatically maps the 52-pin gold finger to the Raspberry Pi’s standard 40-pin GPIO header, simplifying development and deployment. Additionally, the onboard cooling fan improves thermal performance, ensuring stable operation of the Raspberry Pi during continuous use. When combined with an LR1302 gateway module and a Raspberry Pi, this HAT enables users to build a complete and compact LoRaWAN gateway suitable for IoT applications such as smart agriculture, smart cities, and industrial monitoring. Note: LR1302 Gateway Module is not included. Key Features Raspberry Pi CompatibilityDesigned in a standard HAT form factor, fully compatible with Raspberry Pi 1, 2, 3, 4, and 5 series. Integrated GPS & RTCBuilt-in GPS module and real-time clock improve timing accuracy and enable precise positioning for LoRaWAN applications. Simplified IntegrationConverts the 52-pin mini-PCIe interface to a 40-pin GPIO header, allowing easy connection and faster development. Efficient Thermal ManagementEquipped with an onboard cooling fan to maintain optimal operating temperature and enhance system stability. Compact & Space-Saving DesignSmall footprint makes it ideal for embedded and space-constrained IoT gateway deployments.
