E220-230T30D LLCC68 chip 230 MHz Wireless serial LoRa module (UART) TTL level output New generation of LoRa spread spectrum






[Features]:New generation of LoRa spread spectrum

[Introduction]:E220-230T30D adopts a new generation of LoRa spread spectrum technology and is a wireless serial port module (UART) based on LLCC68 chip solution design. It has a variety of transmission methods, works in the (220.125 ~ 236.125MHz) frequency band (default 230.125MHz), TTL level output, compatible with 3.3V and 5V IO port voltage.
