1. Overview

1.1 Introduction

E220-230T30D adopts a new generation of LoRa spread spectrum technology
and is a wireless serial port module (UART) designed on the LLCC68 chip set. It has
a variety of transmission methods, working at 220.125 ～ 236.125MHz (default
230.125MHz), with TTL level output, compatible with 3.3V and 5V IO port voltage.
E220-230T30D adopts a new generation of LoRa spread spectrum technology,
supports air wake-up, carrier sense, communication key and other functions, supports
sub-package length setting, and Ebyte provides customized development services.

1.2 Features

The new LoRa spread spectrum modulation technology developed based on LLCC68, it brings a longer communication distance

and stronger anti-interference ability;
The communication allows users to set key that cannot be read, greatly improving the user data privacy;

Support LBT function, monitor the channel environment noise before sending, which greatly improves the communication

success rate of the module in harsh environments;
Support RSSI signal strength indicator function for evaluating signal quality, improving communication network, and ranging;

Support air wake-up, that is ultra-low power consumption, suitable for battery-powered applications;

Support point to point transmission, broadcast transmission, channel sense;

Support deep sleep, the power consumption of the whole machine is about 5uA in this mode;

The module has built-in PA+LNA, and the communication distance can reach 10km under ideal conditions;

The parameters are saved after power-off, and the module will work according to the set parameters after power-on;

Efficient watchdog design, once an exception occurs, the module will automatically restart and continue to work according to the

previous parameter settings;
Support the bit rate of 2.4k～62.5kbps;

Support 3.0～5.5V power supply, power supply greater than 5V can guarantee the best performance;

Industrial standard design, supporting long-term use at -40～+85℃;

SMA antenna interface.

