1.1 Introduction

E32-400T20S UART wireless modules based on
SX1278 of SEMTECH with transparent transmission
and LoRa spread spectrum technology. SX1278 support
LoRa technology, The LoRa DSSS (direct sequence
spread spectrum) technology features long range and
strong anti-interference
confidentiality. SX1278 are considered as a milestone in
terms of low speed data communication,(default
470MHz) with max 197 bytes per package.SX1278
features LoRa™ technology, LoRa 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 series are 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. 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.
