AI-Thinker LORA RA-02 Spread Spectrum Wireless Module For IOT

Ra-02 is based on SX1278 wireless transparent transmission module (transceiver one), with IPEX socket it can connect external antenna. Using advanced LoRa spread spectrum technology, communication distance is10000 meters, super error correction, anti-interference ability, with the air wake-up function (ultra-low power consumption). It can be used in the enviroment with thousands of people,especially for meter reading, smart home, burglar alarm and other equipment. Feature: LoRa Spread Spectrum Modulation Technology +20dBm-100mW Constant RF power output when voltage changes High sensitivity: low to -148dBm Half-duplex SPI communication Programmable bit rates up to 300kbps Supports FSK, GFSK, MSK, GMSK, LoRa and OOK modulation modes 127dB RSSI dynamic range Automatic RF signal detection, CAD mode and ultra-high-speed AFC With CRC, up to 256 bytes of packet engine Small volume dual-row stamp-hole patch package With shielding shell Spring antenna (Ra-01) or IPEX external antenna (Ra-02) Wireless standard 433MHz Frequency range: 420 ~ 450MHz Interface: SPI GPIO Voltage:1.8 ~ 3.7V, the typical value is 3.3V Current: Receiver:? 10.8mA (LnaBoost off, band 1) Transimit: ? 120mA (+ 20dBm) Sleep mode: 0.2?A Working temperature: -40 to + 85 ?
