This AI-Thinker LoRa module is built on the Semtech SX1278 chip and operates at 433 MHz with a communication range of up to 10 km. Using Semtech's patented LoRa modulation technology, it achieves an exceptional sensitivity of −148 dBm with +20 dBm (100 mW) transmit power, delivering long-range, low-power wireless communication.

The module communicates via half-duplex SPI and supports multiple modulation modes including LoRa, FSK, GFSK, MSK, GMSK, and OOK. Its compact stamp-hole package with shielded housing and included spring antenna makes integration straightforward.
