SX1262 433MHz LoRa Node Module for Raspberry Pi Pico

The SX1262 433M is a LoRa node expansion module designed for the Raspberry Pi Pico supporting the LoRaWAN protocol and EU433 band. The module comes complete with a lithium battery, antenna and connectors to get your project started – just add a Raspberry Pi Pico!

The module can connect to TTN and TTS servers through a LoRa gateway to use the LoRa Cloud service fast and easily with your Pico. Just slot your pico into the pre-soldered female headers to connect the two together, then use the online resources to get started.

On the board, you’ll find an IPEX 1 antenna connector, which can be used with the included IPEX1 to SMA wire and 2DB 433MHz stub antenna (also included). There’s also a power switch, battery connector, LED status indicators and solderable RF switch control.

The package includes the module, a 600mAh 3.7V LiPo battery, 2DB 433MHz stub antenna and an IPEX to SMA cable. We also stock an 868MHz version.

Note: Raspberry Pi Pico not included. You’ll need a Pico with male headers soldered to it. You can grab a Pico here and Pico male headers here, or buy a Pico with pre-soldered headers.
