1. Product Overview

1.1 Product introduction

E22-xxxT30x is a new generation of LoRa wireless modules. This series of (UART) modules are developed based on two
different high-performance radio frequency chips, SX1268 and SX1262 . Its transmit power is: 22dBm and has a variety of
transmission methods. The working frequency bands are respectively 230MHz, 400MHz and 900MHz. LoRa spread spectrum
technology, TTL level output, compatible with 3.3V IO port voltage.
E22-xxxT30x adopts a new generation of LoRa spread spectrum technology. Compared with the traditional SX1276 solution, the
SX1262 and SX1268 solutions have longer transmission distance, faster speed, lower power consumption and smaller size; supporting
air wake-up, wireless Configuration, carrier monitoring, automatic repeater, communication key and other functions; supporting
sub-packet length setting and customized development service is available. The six modules in the picture below have the same power
but different frequency bands.

1.2 Features

Adopting a new generation of LoRa spread spectrum modulation technology, it brings longer communication distance and

stronger anti-interference ability;
Supporting serial port upgrade of firmware , making it more convenient to update firmware;

Supporting AT commands, making it more convenient to use;

Supporting automatic repeater networking, multi-level repeaters are suitable for ultra-long-distance communications, and

multiple networks can run simultaneously in the same area;
Supporting users to set their own communication keys, which cannot be read, greatly improving the confidentiality of user

data;
Supporting LBT function, which monitors the channel environment noise before sending, which can greatly improve the

communication success rate of the module in harsh environments;
Supporting RSSI signal strength indication function for evaluating signal quality, improving communication networks, and

ranging;
