1. Overview
1.1 Introduction
E32-433T20S1 is a wireless serial port module
(UART) based on SEMTECH's SX1278 RF chip. It has
multiple
transmission
modes,
working
in
the
410MHz~441MHz, (default 433MHz), LoRa spread
spectrum technology,
SX1278 features LoRa™, which will bring longer
communication 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.
E32-433T20S1
is in stable bulk production and are widely applied in utility meters, IoT renovation,
smart home, etc. The modules feature data encryption and compression. The data transmitted in air features randomness.
air Data Rate (Default 2.4kps). The encryption-decryption algorithm makes data interception meaningless. And the data
compression enables shorter transmitting time and lower rate of being interfered, which increased the reliability and
transmitting efficiency.
E32-433T20S1 strictly follows design standards of FCC, CE, CCC and meets various RF certification requirements
for exporting.
