Description

E220-400T22S/E220-900T22S 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 and works in the (410.125~493.125MHz) & (850.125-930.125MHz) frequency band respectively, and LoRa spread spectrum technology. The transmission distance is longer, the speed is faster, and the power consumption is lower; it supports functions such as air wake-up, carrier monitoring, communication key, etc., supports sub-package length setting, and provides customized development services.

E220-400T22S/E220-900T22S adopts a new generation of LoRa solution. Compared with the traditional SX1276 solution, the transmission distance is longer, the speed is faster, and the power consumption is lower; it supports functions such as air wake-up, carrier monitoring, and communication key, and supports sub-packet length setting.

Features:

  • Using LLCC68 chip solution has significant advantages of low power consumption, fast speed and long distance;
  • Under ideal conditions, the communication distance can reach 5 km;
  • The maximum transmit power is 22 dBm, and the software is multi-level adjustable;
  • Support users to set the communication key by themselves, and it cannot be read, which greatly improves the confidentiality of user data;
  • Support RSSI signal strength indicator function for evaluating signal quality, improving communication network, and ranging;
  • Support air wakeup, that is, ultra-low power consumption function, suitable for battery-powered applications;
  • Support fixed-point transmission, broadcast transmission, channel monitoring;
  • Support the global ISM 443/868/915MHz frequency band;
  • The parameters are saved after power off, and the module will work according to the set parameters after power on again;
  • Efficient watchdog design. Once an exception occurs, the module will automatically restart and continue to work according to the previous parameter settings;
  • Support the data transmission rate of 2.4k~62.5kbps;
  • Support 2.3~5.5V power supply, power supply greater than 5V can guarantee the best performance;
  • Industrial standard design, supporting long-term use at -40~+85C;
  • Dual antennas are optional (IPEX/stamp hole), which is convenient for users to develop and integrate.
