This LoRa HAT, suitable for the Raspberry Pi, is based on the SX1262 and covers the 868 MHz frequency band. It allows data transmission up to 5 km via the serial interface.
By using the new generation of LoRa spread spectrum modulation technology, the communication range of the module is up to 5 km, also supports automatic retransmission to transmit longer. Other features include Wake on Radio, wireless configuration, carrier detection, communication key and so on.
Compared to normal LoRa modules, the SX1262 LoRa HAT achieves a greater communication range, higher rate, lower consumption, better security and anti-interference. It is suitable for various applications like industrial control, smart home, data acquisition, etc.
Features
• onboard CP2102 USB - UART converter, for serial debugging
• brings the UART control interface for connecting host boards like Arduino/STM32
• 4x LED displays, easy to check module status
• LoRa spread spectrum modulation technology, up to 84 available signal channels, greater communication range, more robust against interference
• automatic multi-level replay, suitable for extremely long range communication, allows multi-network on the same region
• low power consumption features like deep sleep and wake on radio, ideal for battery powered applications
• customizable communication key that cannot be retrieved significantly improves the security of user data
• supports LBT, monitors signal channel noise before transmission, significantly improves success rate under extreme conditions
• supports RSSI signal intensity, which indicates network tuning to assess signal quality
• supports the configuration of wireless parameters by sending a wireless command/data packet, remote configuration or retrieving the module parameters
• supports fixed point transmission, broadcast, signal channel monitoring
• comes with development resources and manual (examples for Raspberry Pi/STM32)
• for all common Raspberry Pi variants
