[Introduction]：E220-400T30S is a wireless serial port module (UART) based on SEMTECH's LLCC68, working at 410.125～493.125MHz（ default 433.125MHz）, TTL level output, compatible with 3.3V and 5V IO port voltage
Partial Function Introduction of E220 Series
E220 series is professionally developed based on SEMTECH chip solution: SEMTECH LLCC68 original imported chip is used, compared with the traditional SX1278 solution, the transmission distance is longer, the speed is faster, and the power consumption is lower
Adopt new LoRa spread spectrum technology: anti-interference, longer transmission distance, and ensure communication stability
Global license-free ISM frequency band 433/470/868/915MHz: E220 series use a wide range of frequencies to meet the needs of various applications
E220 supports a variety of transmission methods: fixed-point transmission, broadcast transmission, and channel monitoring communication methods can be freely set according to requirements
Support air wake-up, effectively achieve low power consumption, greatly reduce the power consumption of the receiving end, suitable for battery-powered applications
Support RSSI signal strength indication function: it can be applied to evaluate signal quality, improve communication network, distance measurement and other operations.
The E220 series has two types of antennas: dual antennas can be selected (IPEX/stamp hole), which is convenient for integration and secondary development.
Smaller volume and easier integration: E220 series adopts highly integrated circuit design, coupled with reasonable PCB layout, which greatly reduces the volume of developed products.
E220 series are equipped with professional radio frequency shielding cover: the alloy metal cover surrounds the receiving circuit and components to prevent them from being affected by the external electromagnetic field, so as to achieve the effect of anti-interference and anti-static.
