SKU: ACR-00047 Categories: , , Tags: , ,


The SX1276/77/78/79 transceivers feature the LoRa long range modem that provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption.

As the SX127x chips needs a few additional components for operation, the Ra-02 module developed by A.I. Thinker includes an SX1278 and everything needed for it to work in a small form factor PCB. This breakout board facilitates developing/prototyping with the Ra-02 module tremendously. Solder the pins, plug it into a microcontoller/SoC using dupont wires or a solderless breadboard, and use it to create LoRa projects!
