SX1262 LoRaWAN Node Module Expansion Board for Raspberry Pi, With Magnetic CB antenna, frequency: 868/915MHz With GNSS Function
SX1262 LoRaWAN/GNSS HAT
SX1262 RF Chip LoRa Module, Suitable For Sub-GHz Band Network
Features At A Glance
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.
Common features:
- Standard Raspberry Pi 40PIN GPIO header, supports Raspberry Pi series boards
- The new generation SX1262 has higher power efficiency and longer transmission distance than the SX1278
- Suitable for Sub-GHz band, combined with the gateway, can be quickly connected to a cloud server such as TTN to build a LoRaWAN network
GNSS version features:
- Onboard L76K module with GPS/BD support, provides accurate clock and location info for node module
- Onboard button cell holder, supports ML1220 rechargeable cell, for preserving ephemeris information and hot starts
- Onboard 4 LED indicators for module operating status
- Comes with online development resources and manual (example in C)
