1 Product Overview
1.1 Product Introduction
E22-230T30E, E22-230T33E, E22-400T30E, E22-400T33E are the new generation of LoRa wireless spread
spectrum modules. Among them, E22-230T30E and E22-230T33E are based on the wireless serial port module designed
by SEMTECH's SX1262 chip scheme, while E22-400T30E and E22-400T33E are based on SX1268 chip scheme. It has
a variety of transmission modes. E22-230T30E and E22-230T33E work in the 220.125
～
236.125MHz frequency band
(230.125MHz by default), E22-400T30E and E22-400T33E work in the 410.125
～
493.125MHz frequency band
(433.125MHz by default), LoRa spread spectrum technology, compatible with 3.3V and 5V IO port voltage, MINI PCI-e
standard packaging, UART/RS485/RS232/USB communication interface selection, and communication is compatible
with E22-T series products, facilitating user development and use.
E22-230T30E , E22-230T33E , E22-400T30E , E22-400T33E adopt a new generation of LoRa spread spectrum
technology. Compared with the traditional SX1278 solution, this solution has a longer transmission distance and faster
speed; it supports air wake-up, wireless configuration, and carrier monitoring , automatic relay, communication key and
other functions, support subpackage length setting, and can provide customized development services.
Note: The above picture is the 3D size drawing of the E22-230T30E module , and the other modules are the same
size, pin compatible, and different in frequency band and power.
1.2 Features
On the new LoRa spread spectrum modulation technology developed by SEMTECH 's SX1262 and SX1268 RF
chips , it brings longer communication distance and stronger anti-interference ability;
Automatic relay networking, multi-level relay is suitable for ultra-long-distance communication, and multiple
networks run simultaneously in the same area;
Support users to set the communication key by themselves, and it cannot be read, which greatly improves the
Frequency
Power
