About this product
The Ai-Thinker Ra-02 is a surface-mount LoRa transceiver module based on the Semtech SX1278, operating between 410 and 525 MHz. It connects to a host microcontroller over SPI, runs from a 2.7 V to 3.6 V supply and takes an external antenna through an IPEX connector for long-range low-rate telemetry.
