Hot selling original stock sale E220P-400T22S LoRa spread spectrum technology wireless transmission monitoring
E220P-400T22S is a new generation of LoRa wireless module(UART), based on Semtech's original LLCC68 chip design.
Product Descriptions
E220P-400T22S 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,The module has built-in PA+LNA, and the communication distance can reach 7km
under ideal conditions. (E220P-400T22S is 5.6km) built-in LNA and ESD receiver, with stronger anti-interference ability and longer receiving distance. Using active crystal oscillator, frequency deviation ±1PPM, can normal communication under high
temperature and low temperature conditions. works in the (410.125 ~ 493.125MHz) frequency band (default 433.125MHz), LoRa spread spectrum technology, TTL level output, compatible with 3.3V and 5V IO port voltage.
E220P-400T22S 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. Ebyte can provide customized development services. Compared with the LLCC68 scheme, this scheme has a high cost performance advantage. The product can cover an ultra-
wide frequency range of 410~493MHz.
Product Features
Using LLCC68 chip solution, it has significant advantages of low power consumption, fast speed and long distance;
Under ideal conditions, the communication distance can reach 5km;
The maximum transmit power is 22dBm, 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 433/470MHz frequency band;
The module has built-in PA+LNA, and the communication distance can reach 7km under ideal conditions. (E220-400t22s 5.6 km)
Built-in LNA and ESD receiver, stronger anti-interference ability, longer receiving distance. Using active crystal oscillator, frequency deviation ±1PPM, can normal communication under high temperature and low temperature conditions. 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 3.3~5.5V power supply, power supply greater than 5V can guarantee the best performance;
Industrial standard design, supporting long-term use at -40~+85℃;
Dual antennas are optional (IPEX/stamp hole), which is convenient for users to develop and integrate.
