SX1278 LoRa Module 433Mhz ( Ra-01 )

SX1278 LoRa Module 433Mhz Anxin LoRa series module (Ra-01/Ra-02) was designed and developed by Anxinke Technology, this series of modules The RF chip SX1278 mainly uses LoRaTM remote modem for ultra long-range spread spectrum Letter , anti- interference is strong, it is possible to minimize current consumption.With SEMTECH's LoRaTM With modulation technology, the SX1278 has a high sensitivity of over -148dBm and a power output of +20dBm. , Transmission distance stay away, high reliability. At the same time, LoRaTM modulation technology is resistant to traditional modulation techniques. Blocking and selection also have obvious advantages, which solves the problem that traditional design solutions cannot take into account the distance at the same time. Anti-interference and power consumption issues. Ra-01, Ra-02 operating frequency 433M, mainly for 433M network Segments of the region , including China and Southeast Asia. Module characteristics: LoRaTM 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 methods 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 shielding shell Spring antenna (Ra-01) or IPEX external antenna (Ra-02)
