SMD LoRa Module Ra 01S Ai Thinker

The Ai-Thinker Ra-01S is a professional-grade LoRa transceiver module designed for ultra-long distance wireless communication applications. Built around Semtech's advanced SX1268 RF chip, this module delivers exceptional performance with high sensitivity of -148dBm and powerful +22dBm output capability. The module operates in the 410-525MHz ISM frequency band and utilizes LoRa™ patented modulation technology to achieve reliable communication over several kilometers. With its low power consumption characteristics (4.5mA receiving current, 1.6mA standby), it's ideal for battery-powered IoT applications. The module features a standard SPI interface for easy integration with microcontrollers, supports half-duplex communication, and includes CRC error checking with up to 256-byte packet handling. Its compact 16x17mm SMD package makes it perfect for space-constrained designs. Choose the Ra-01S for your remote sensing, smart agriculture, industrial monitoring, or any application requiring reliable long-range wireless connectivity with minimal power consumption.
