Documentation notice: This technical documentation was independently rewritten from an archived supplier source. Check technical details and commands against the product version and manufacturer documentation before use.

Summary

The Waveshare Pico-LoRa-SX1262 is a LoRa node module based on the Semtech SX1262 chip, designed specifically for the Raspberry Pi Pico. It supports the LoRaWAN protocol and, in the supplied variant, is configured for the EU868 frequency band. The module features its own battery holder with a charging controller, two status LEDs, and communicates with the microcontroller via the SPI interface.

Connects to the Pico via dedicated GPIO pins for SPI, interrupt, reset, and battery sensing

Notes and version constraints

The exact pin mapping (GP26, GP20, GP15, GP12, GP11, GP10, GP3, GP2) must be verified against the current hardware documentation before integration.
The SPI bus should be operated below 18 MHz; specific timing requirements follow Chapter 8 of the SX1262 datasheet.
Using OTAA requires valid AppEUI/DevEUI values from the server; these are not included in the source text.
Selection of the frequency band (e.g., EU868 vs. EU433) depends on local radio regulations and must be confirmed for the deployment location.
