RA-01 LoRa RF Module (Ai-Thinker)

The RA-01 LoRa module by Ai-Thinker is a compact, high-performance wireless communication module based on the Semtech SX1278 LoRa transceiver. It operates in the ISM band (typically 410–525 MHz) and is designed for long-range, low-power communication applications. The module supports LoRa, FSK, and OOK modulation, enabling flexible wireless solutions for IoT systems. Its small size and SPI interface make it easy to integrate with microcontrollers for reliable long-distance data transmission.
