Ebyte E220P-400T22S LLCC68 433~470MHz 22dBm LoRa Wireless Module

Ebyte E220P-400T22S LLCC68 433~470MHz 22dBm LoRa Wireless Module

E220P-400T22S adopts the new generation of LoRa spread spectrum technology, a wireless serial port module (UART) designed based on LLCC68 RF chip solution, and a built-in LNA, active temperature compensated crystal oscillator and receiving limiter in the wireless module. Under ideal conditions, the communication distance can reach 7km (5.6km for E220-400T22S), with stronger anti-interference ability and longer receiving distance. It supports functions such as air wake-up, carrier monitoring, communication key, and sub-packet length setting, and can provide customized development services.

Datasheet

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.
