1. Overview
1.1
Introduction
E32-170T30D is a wireless serial port module
(UA RT) based on SEMTECH's SX1278 RF chip. LoRa
spread spectrum technology, TTL level output,
compatible with 3.3V and 5V
(
reco mmendation
4.75-5.5 V
)
,It has a great penetration ability. The
correcting ability on the software can be largely
increased at against disturbing.
SX1278 features LoRa ™, also it can bring longer communication distance, and has the advantages of concentrated
power density, meanwhile it has a very strong confidentiality. The modules of 30d Bm trans mitting power are embedded
with power amp lifier (PA) and lo w noise amp lifier (LNA), wh ich enhances the stability and longer co mmunication range;
the modules of 30d Bm transmitting power adopt industrial grade crystal oscillators to ensure the stability and consistency,
its precision is lower than the widely adopted 10ppm. It is in stable bulk production and are widely applied in utility
meters, IoT renovation, smart ho me, etc. The modules feature data encry ption 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 lo wer rate of being interfered, which increased the reliab ility and
transmitting efficiency.
E32-170T30D strictly fo llows design standards of FCC, CE, CCC and meets various RF certification requirements
for exporting.
