Introduction
E220P-400T22S is a new-generation LoRa wireless serial port module (UART) based on the Semtech LLCC68 chip. It supports multiple transmission modes with a built-in PA + LNA, achieving a communication range of up to 7km under ideal conditions (the E220P-400T22S features a built-in LNA and ESD receiver for enhanced interference immunity and extended reception range). Using an active crystal oscillator with a frequency deviation of ±1PPM, it operates reliably under both high- and low-temperature conditions. Operating in the 410.125 ~ 493.125MHz band (default: 433.125MHz), it employs LoRa spread spectrum technology with TTL-level output, compatible with both 3.3V and 5V IO port voltages. This module adopts a new-generation LoRa solution that offers longer transmission range, faster speed, and lower power consumption compared to the traditional SX1276 solution. It supports air wake-up, carrier sensing, communication key, and configurable sub-packet length. EBYTE provides customized development services. Compared to the LLCC68 solution, this solution offers a high cost-performance advantage with product coverage across an ultra-wide frequency range of 410 ~ 493MHz.
Features
