Ebyte E220-900T22S UART/LLCC68 850.125/930.125MHz 22dBm LoRa Wireless Serial Port Module

Ebyte E220-900T22S UART/LLCC68 850.125/930.125MHz 22dBm LoRa Wireless Serial Port Module

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, works in the (850.125～930.125MHz) frequency band (default 873.125MHz), LoRa spread spectrum technology, TTL level output, compatible with 3.3V and 5V IO port voltage.

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. 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 850～930Mhz.

User Manual

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 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
