E220-230T30S New-Gen LoRa serial module LLCC68 chip solution LoRa spread spectrum technology TTL level output






[Features]:New generation of LoRa technology

[Introduction]:E220-230T30S is a new generation of LoRa wireless serial port module (UART), based on Semtech's original LLCC68 chip solution design. It has a variety of transmission methods, works in the (220.125 ~ 236.125MHz) frequency band (default 230.125MHz), LoRa spread spectrum technology, TTL level output, compatible with 3.3V and 5V IO port voltage.
