1. Overview

1.1 Introduction

E220-400T30S is a wireless serial port module (UART) based on
SEMTECH's SX1268, working at
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.

1.2 Features

⚫ 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.
⚫ Supports air date rate of 2.4kbps～62.5kbps；
⚫ Supports 3.0V~5.5V power supply, power supply over 5.0 V can guarantee the best performance；
⚫ Industrial grade standard design, support -40 ~ 85 °C for working over a long time；
⚫
Dual antenna (IPEX and stamp hole) optional, good for secondary development and integration.
