JESSINIE 2Pcs SX1278 LoRa Ra-02 Wireless Module 433MHz Ra-02 Spread Spectrum Wireless Module Serial Port Adapter 3.3V UART Interface with Connector

Description

• LoRa modem supports FSK, GFSK, MSK, GMSK, LoRa and OOK modulation methods
• Support frequency band 410MHz ~ 525MHz, working voltage 3.3V, maximum output 20dBm, maximum working current 105mA
• It has low power consumption characteristics in the receiving state, the receiving current is 12.15mA, the standby current is 1.6mA, and the high sensitivity is as low as-140dBm
• The module uses SPI interface, half-duplex communication, CRC, up to 256 bytes of packet engine
• Power supply range: 2.7~3.6V, typical value 3.3V, current greater than 200mA; Programmable bit rate up to 300kbps; Spectrum range 410MHz ~ 525MHz

The module is used for ultra-long-range spread spectrum communication, and its RF chip SX1278 mainly uses LoRa remote modem for ultra-long-range spread spectrum communication, which has strong anti-interference and can minimize current consumption. With the help of SEMTECH LoRa patented modulation technology, SX1278 has a high sensitivity exceeding-148dBm, a power output of 20dBm, a long transmission distance and high reliability. At the same time, compared with traditional modulation technology, LoRaModulation technology also has obvious advantages in anti-blocking and selection, which solves the problem that traditional design schemes cannot take into account distance, anti-interference and power consumption at the same time.
Applications are used for automatic meter reading, home building automation, security systems, and remote irrigation systems.
