Ra-02 LoRa Module 433MHz 10KM Ai-Thinker Wireless Transmission

SX1278 LoRa Module 433M 10KM Ra-02 Ai-Thinker Wireless Spread Spectrum Transmission Socket for Smart Home DIY The SX1278 LoRa spread spectrum wireless module uses the Enxin LoRa series module Ra-02. The interface is compatible with the NRF24L01 module. If you want to transfer data over long distances, you can directly replace the NRF24L01. Just change the program and do not need to change the hardware design. LoRa series module (Ra-01/Ra-02), the module of this series RF chip SX1278 mainly uses LoRaTM remote modem for ultra long-range spread spectrum communication. Strong anti-interference ability to minimize current consumption. LoRa modulation with SEMTECH Technology, SX1278 has a high sensitivity of over -148dBm, +20dBm power output, transmission distance Far away, high reliability. At the same time, compared to traditional modulation techniques, LoRaTM modulation technology is anti-blocking and selection. The aspect also has obvious advantages, which solves the problem that the traditional design scheme cannot balance distance, anti-interference and power consumption at the same time. The problem. Ra-01, Ra-02 operating frequency 433M, mainly for the 433M network segment SX1278 features: • LoRa Spread Spectrum Modulation Technology • Ultra-long communication distance 15KM • Constant RF power output with +20dBm-100mW voltage change • High sensitivity: as low as -148dBm • Half-duplex SPI communication • Programmable bit rate up to 300kbps • Support FSK, GFSK, MSK, GMSK, LoRaTM and OOK modulation • 127dB RSSI dynamic range • Automatic RF signal detection, CAD mode and ultra-high speed AFC • Packet engine with CRC up to 256 bytes • Small size double column stamp hole patch package • With shield • Spring antenna (Ra-01) or IPEX external antenna (Ra-02) category parameter Description Wireless parameter Standard certification FCC/CE Wireless standard 433MHz Frequency Range 420~450MHz Hardware parameter Data connection ?
