1. Overview
1.1 Introduction
E220-230T30S is a new generation of Lora wireless serial port module
(UART) based on SEMTECH's LLCC68, working at 220.125
～
236.125MHz
(default 230.125MHz), with TTL level output, compatible with 3.3V and 5V IO
port voltage.
Compared with the traditional SX1278 solution, it has a longer transmission
distance, faster speed, lower power consumption; it supports functions such as air
wake-up, carrier sense, communication keys and sub-package length setting. Ebyte provides customized development
services on it. It is a cost-effective solution, which covers the frequency band of 220 ~ 236MHz.
1.2 Features

LLCC68 LoRa chip has the advantage of low power consumption, fast speed and long distance;

In ideal condition, communication distance reach up to 10 km
；

Maximum transmission power of 30dBm, software multi-level adjustable
；

The communication allows users to set key that cannot be read, greatly improving the user data privacy;

Supports RSSI for evaluating signal quality, improving communication network, and ranging;

Support air wake-up, that is, ultra-low power consumption function, suitable for a battery-powered application
solutions;

Supports fixed transmission, radio transmission, channel to monitor;

Parameters automatically saved when power off, it will work according to previous parameters once powered on.

Effective watchdog design, once an exception occurs, the module will be in automatic restart, and can continue to
work on previous parameter;

Supports air date rate of 2.4kbps
～
62.5kbps
；

Supports 2.3V~5.5V power supply, power supply over 5.0 V can guarantee the best performance
；
