SX1278 LoRa Module 433Mhz

Mini SX1278 LoRa Transceiver Module Description: The "XL1278-SMT" module that I got is a type of low-cost RF front-end transceiver module based on the SX1278 from Semtech Corporation. It keeps the advantages of RFIC SX1278 but simplifies the circuit design and is suitable for low-range and low-data-rate applications. The "mini SX1278 LoRa 5-Km wireless transceiver module" from Banggood consists of one RFIC SX1278, a thin SMD crystal, and an antenna matching circuit. The antenna port is well-matched to a standard 50- impedance, and a spring coil antenna (designed for 433 MHz) is also included in the packet. This module is a type of low cost RF front-end transceiver module based on SX1278 from Semtech Corporation. It keeps the advantages of RFIC SX1278 but simplifies the circuit design. The high sensitivity (-136dBm) in LoRa modulation and 20dBm high power output make the module suitable for low range and low data rate applications. The module consists of RFIC SX1278, thin SMD crystal and antenna matching circuit. The antenna port is well matched to standard 50 Ohm impedance. Users don't need to spend time in RF circuit design and choose suitable antennas for different applications. The module operates at 1.8~3.6V with extra low standby current which makes it suitable for battery powered-up applications. Because it is purely hardware module and it adopts 10ppm crystal which the resolution of it places a important role in calculating spreading factor, bandwidth, etc. Features: FSK/GFKS technology, LoRa (remote) spread spectrum technology Half duplex communication Strong anti-interference (channel rejection ratio: 56db) High receiving sensitivity - 139dbm. (32M passive 10ppm crystal) ISM multi-band, no need to apply for free frequency. Multi-frequency optional, multiple transmission rates. Can be applied in FDMA and FM technology. Intelligent reset, low voltage monitoring, timed wake up, low power mode, sleep mode Low power receiving current: 10-12mA 256 -bit FIFO TX/RX RSSI channel detection function Transmission mode: FIFO / direct mode (recommended FIFO packet mode) Configuration: AFC / air wake up function / low power / carrier sense / FEC error correction / AEC encryption Long distance transmissionThe space is up to 5km Module size: 22.8 x 22.7 x 4.2mm
