E220-900T30S LLCC68 chip LoRa wireless serial port module LoRa spread spectrum technology






[Product weight]:5.1g±0.1g

[Introduction]:E220-900T30S 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 (850.125~930.125MHz) frequency band(default 873.125MHz), LoRa spread spectrum technology, TTL level output, compatible with 3.3V and 5V IO port voltage.
