 Eason wireless module

RF wireless module yl-1276rf

Chip solution :Sx1276
carrier frequency :433M/868M/915M
Transmitting power : high power 2W
Communication distance : sight distance 3-5km
Product size :26mm*40mm*3mm
communication interface :SPI
Product introduction This is a dual power amplifier radio frequency wireless module based on Semtech sx1276, which integrates transmitter and receiver, and single module can be transmitted and received. When Lora spread spectrum modulation is used in the module, it has very high receiving sensitivity. Therefore, under the same transmission power, it has lower power consumption, longer distance and stronger anti-interference ability than other wireless schemes. the module is not equipped with single-chip microcomputer and provides SPI communication interface. Users do not need to understand too complex RF knowledge and do not need to do hardware debugging. They only need to debug the underlying SPI communication and understand the meaning of the function well, then they can easily apply this module. The module integrates two PA, which is suitable for 433 band, 868 band and 915 band, with maximum output power of 2W.
