LLCC68 RS485 Wireless RF Transceiver and Receiver 433MHz 470MHz 30dBm IoT LoRa Spread Spectrum Module Long Range






[Product weight]:10.2g±0.1g

[Introduction]:The E220-400R30D uses a new generation of LoRa spread-band technology based on the RS485 module designed for the LLCC68 chip scheme LLCC68 chip scheme with a variety of transmission modes. It operates in the (410.125 to 493.125MHz) frequency (default 433.125MHz) and supports DC 5.0 power supply.
