Chapter 1 Overview

1.1 Product Introduction

E22-230T30D is a new generation LoRa wireless module, based on
SEMTECH SX1262 RF chip wireless serial module (UART), with a variety
of transmission methods, working in the (220.125 ~ 236.125MHz)
frequency band (default 230.125MHz), LoRa spread spectrum technology,
TTL level output, compatible with 3.3V and 5V IO port voltage.
E22-230T30D adopts the new generation LoRa spread spectrum technology, compared with the traditional SX1276
solution, SX1262 solution has longer transmission distance, faster speed, lower power consumption and smaller
size; it supports wake-on-air, wireless configuration, carrier listening, automatic relay, communication key and
other functions, supports sub-packet length setting, and can provide custom development services.

1.2 Features

Develops new LoRa spread spectrum modulation technology based on SX1262, which brings longer communication
distance and stronger anti-interference capability;
Supports auto-relay networking, multi-level relay for ultra-long distance communication and multiple networks
running simultaneously in the same area;
Supports user-set communication key, and it cannot be read, which greatly improves the confidentiality of
user data;
Supports LBT function to listen to the channel environment noise before sending, which can greatly improve
the communication success rate of the module in harsh environment;
Supports RSSI signal strength indication function for evaluating signal quality, improving communication
network and ranging;
Supports wireless parameter configuration, sending command packets over the air to remotely configure or
read wireless module parameters;
Supports over-the-air wake-up, i.e., ultra-low power consumption function, for battery-powered application
solutions;
Supports fixed-point transmission, broadcast transmission, and channel monitoring;
Supports deep hibernation, the power consumption of the whole unit in this mode is about 2uA;
Supports 230MHz power band, with better penetration and bypass capability than 433MHz;
Module built-in PA+LNA, communication distance up to 10km under ideal conditions;
Parameters are saved at power-down, and the module will work according to the set parameters after re-powering;
Efficient watchdog design, once the abnormality occurs, the module will restart in automatically and can
continue to work according to the previous parameter settings;
Supports data transfer rates from 2.4k to 15.6kbps;
