1 Introduction

1.1 Brief Introduction

E22-230T22D is a new generation of LoRa wireless module, based on
SEMTECH SX1262 RF chip wireless serial module (UART), with multiple
transmission modes, working in 220.125 ~ 236.125MHz frequency band
(default 230.125MHz), LoRa spread spectrum technology, TTL level
output, compatible with 3.3V and 5V voltage.
E22-230T22D 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

Development of new LoRa spread spectrum modulation technology based on SX1262, bringing longer communication distance

and better anti-interference capability.
Support for automatic relay networking, multi-level relay for ultra-long-distance communication, multiple networks running

simultaneously in the same area.
Support users to set their own communication key and it cannot be read, which greatly improves the confidentiality of user data.

Support LBT function to listen to the channel environment noise before transmitting, which can greatly improve the

communication success rate of the module in harsh environment.
Support RSSI signal strength indication function for evaluating signal quality, improving communication network, ranging.

Support wireless parameter configuration, send command packets via wireless to remotely configure or read wireless module

parameters.
Support for over-the-air wake-up, i.e., an ultra-low power function for battery-powered application solutions.

Support for fixed-point transmission, broadcast transmission, and channel monitoring.

Support deep hibernation, the power consumption of the whole machine in this mode is about 2uA.

Support 230MHz power band with better penetration and bypassing capability than 433MHz.

Communication distances of up to 5 km under ideal conditions.

The parameters are saved at power-down, and the module will work according to the set parameters after re-powering.

Efficient watchdog design, in the event of an abnormality, the module will restart automatically and will continue to work

according to the previous parameter settings.
Support data transfer rates from 0.3k to 15.6kbps.

Support 2.3 to 5.5V power supply, greater than 3.3V power supply can ensure the best performance.

Industrial-grade standard design, supporting long time use at -40 to +85°C.

Dual antennas are optional (IPEX/stamp hole) for user-friendly secondary development and easy integration.
