1. Overview
1.1 Introduction
E220-400T30S is a wireless serial port module (UART) based on
SEMTECH's SX1268, working at
433.125
, 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, and smaller size; it supports functions such as air wake-up, wireless configuration, carrier monitoring,
automatic relay. communication keys and sub-package length setting. Ebyte provides customized development services
on it. An obvious advantage is that SX1268 covers wider frequency range.

SX1268 LoRa chip brings lower power consumption, further communication distance and stronger anti-interference
ability;
Communication distance tested is up to 10 km
；
software multi-level adjustable
；
The communication allows users to set key that cannot be read, greatly improving the user data privacy;
Wireless parameters configuration, sent via wireless instruction packet, or read a wireless remote configuration
module parameter;
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;
Supports the global license-free ISM 433MHz for global meter reading
；
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 RSSI for evaluating signal quality, improving communication network, and ranging;
Supports LBT for monitoring channel environmental noise before sending data, and for improving communication.
