Waveshare SX1262 LoRa Expansion HAT Long Range 868MHz LoRa HAT For Raspberry Pi - RS8472

Description:

This Raspberry Pi LoRa Expansion HAT utilizes the Semtech SX1262 transceiver, providing robust 868MHz LoRa connectivity. It supports serial data transmission over distances up to 5 kilometers. Employing the latest LoRa spread spectrum modulation, the HAT offers extended range and includes an auto-repeating function for even greater distances.

Additional features encompass Wake on Radio for low-power operation, wireless parameter configuration, carrier sense capability, and communication encryption. The SX1262 chipset delivers significant advantages over conventional LoRa modules, including increased data rates, reduced power consumption, enhanced security, and improved immunity to interference. Suitable for industrial IoT, smart agriculture, and remote monitoring solutions.
