SX1262 LoRaWAN Node Module Expansion Board for Raspberry Pi (850~930MHz HF with GNSS)

This module is a feature-packed expansion board that empowers your Raspberry Pi with great communication capabilities, equipped with the SX1262 LoRa transceiver (850~930MHz HF) , providing long-range communication for IoT (Internet of Things) applications. The magnetic CB antenna provides reliable and stable LoRaWAN communication. Onboard is a Sub-GHz frequency band support that allows seamless integration with various LoRaWAN networks, expanding your reach and ensuring robust data transmission in diverse environments.

Also included is the GNSS (Global Navigation Satellite System) functionality, incorporating the L76K module with GPS/BD (BeiDou) support. This allows precise geolocation and tracking capabilities. To give convenience, it includes a button cell holder, providing backup power to the module in case of power outages or during low-power operation.

This module is an invaluable tool for your Raspberry Pi-based IoT projects, offering a comprehensive solution for long-range communication, accurate positioning, and robust connectivity. Whatever project you’re working on next, this expansion board provides the crucial connectivity and features needed to transform your Raspberry Pi into a powerful LoRaWAN node.

Note: The Raspberry Pi is NOT included
