E220-400T22S LLCC68 LoRa Wireless RF Module 22dBm ISM band 433MHz LoRa Spread Spectrum SMD IPEX Antenna Anti-interference






[Product weight]:2.2g±0.1g

[Introduction]:E220-400T22S is a new generation of LoRa wireless serial port module (UART), based on Semtech's original LLCC68 chip design. It has a variety of transmission methods, works in the (410.125~493.125MHz) frequency band (default 433.125MHz), LoRa spread spectrum technology, TTL level output, compatible with 3.3V and 5V IO port voltage
