1. Overview
1.1 Introduction
E32-433T20DC is a wireless serial port module
(UA RT) based on SEMTECH's SX1278 RF chip. It has
multip le transmission modes, working in the
410M Hz~441MHz, (default 433MHz), LoRa spread
spectrum technology,
SX1278 features LoRa ™, which will bring longer
communicat ion distance, and has the advantages of concentrated power density, meanwhile it has a very strong
confidentiality. the modules of 20dBm transmitting power adopt industrial grade crystal oscillators to ensure the stability
and consistency, its precision is lower than the widely adopted 10ppm. E32-433T20DC is in stable bulk production and
are widely applied in utility meters, IoT renovation, smart home, etc. The modules feature data encry ption and
compression. The data transmitted over the air features randomness. The encryption-decryption algorithm makes data
interception mean ingless. Data compression enables shorter transmitting time and lower rate of being interfered, which
increases the reliability and transmitting efficiency.
E32-433T20DC strictly follows design standards of FCC, CE, CCC and meets various RF certification
requirements for exporting.
