1. Overview
1.1 Introduction
E22-900T22D is a wireless module (UART) with multiple transmission
modes, working in the 850.125MHz~930.125MHz, (default 868.125MHz). It
features LoRa spread spectrum technology, TTL level output, compatible with
3.3V and 5V IO port voltage.
E22-900T22D adopts a new generation of LoRa spread spectrum
technology. Compared with the traditional SX1278 solution, it has a longer
transmission distance, faster speed, lower power consumption, and smaller size; it supports functions such as air wake-up,
wireless configuration, carrier monitoring, automatic relay. communication keys and sub-package length setting. Ebyte
provides customized development services on it.
1.2 Features
 New LoRa spread spectrum modulation technology brings further communication distance and stronger
anti-interference ability;
 Supports automatic relay network, multilevel relay used in long distance communication, the same area to run
multiple network running at the same time;
 The communication allows users to set key that cannot be read, greatly improving the user data privacy;
 Supports LBT function, before sending channel environmental noise monitoring, can greatly increase the success
rate of communication module in harsh environment;
 RSSI signal strength indicator function, can be used to assess the signal quality, improve the communication
network and distance;
 Wireless parameters configuration, sent via wireless instruction packet, or read a wireless remote configuration
module parameters;
 Air wake up, that is, ultra-low power consumption function, suitable for a battery-powered application solutions;
 Supports fixed transmission, radio transmission, channel to monitor;
 Deep sleep mode enables 2 ua power consumption;
 Global free license ISM 868/915 MHZ band;
 Under ideal conditions, the communication distance can be up to 5 km;
 Supports parameter electricity saving, electricity again after the module will work according to set good parameters;
 Effective watchdog design, once an exception occurs, the module will be in automatic restart, and can continue to
work on previous parameter;
 0.3 k ~ 62.5 kbps air data rate;
 2.3 V to 5.5 V power supply, over 5V power supply can ensure the best performance;
 Industry-standard design, support - 40 ~ + 85 ℃ under long time use;
