- Ra-02 is based on SX1278 wireless transparent transmission module (transceiver one), 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.
- 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) external antenna (Ra-02)
