Wave Pi Pico LoRa Node - 433MHz

The Wave Pi Pico LoRa Node - 433MHz is a LoRa node expansion module for Raspberry Pi Pico, built around the SX1262 chipset. Compared to the SX127X series, it offers better performance, higher sensitivity, and lower power consumption. It supports the LoRaWAN protocol, enabling seamless integration with TTN, ChirpStack, and other LoRa Cloud services through a compatible LoRa gateway.



Designed for long-range communication with excellent interference immunity, this module supports FSK, GFSK, and LoRa modulation. It features an onboard PH1.25 battery header with a charging controller, allowing connection to a rechargeable lithium battery for mobile applications. The module is equipped with a temperature-compensated crystal oscillator for stable operation under extreme temperature conditions.
