SX1262 433/470MHz LoRaWAN Node Module Expansion Board for Raspberry Pi, With Magnetic CB antenna & GNSS Function
This series of products are LoRa modules using the new generation of SX1262 RF chip, with the features of long communication distance and strong anti-interference ability. Suitable for Sub-GHz frequency band network, and is available in LF (410~510MHz) or HF (850~930MHz) frequency band versions. Combined with a LoRa gateway, it can be connected to servers such as TTN to build a LoRaWAN network. In addition to the basic LoRaWAN version, it also provides optional GNSS positioning function with GPS/BD support.
