Ai-Thinker RA-01S SX1268 LoRa Module – Long Range Wireless Transceiver
The Ai-Thinker RA-01S is a compact and powerful LoRa™ wireless module designed for ultra-long-range communication, integrating Semtech’s SX1268 transceiver chip. It offers robust signal transmission with a +22dBm RF output power and high sensitivity of -140dBm, enabling long-range and highly reliable data transfer.
The RA-01S supports multiple modulation schemes including FSK, GFSK, MSK, GMSK, LoRa™, and OOK, making it versatile for various wireless communication environments. Its SPI interface allows easy integration with microcontrollers and embedded platforms.
Designed with a small SMD-16 package and available in a 17×16mm form factor, this module is ideal for use in automated meter reading, smart home devices, security systems, and remote irrigation applications. It is built for power-efficient operation with just 4.5mA in receive mode and 1.6mA in standby.
Thanks to LoRa™’s spread spectrum technology, the RA-01S overcomes the limitations of traditional wireless designs, offering greater anti-interference, low power consumption, and signal robustness, even in noisy environments.
