1. Overview
1.1 Introduction
E32-868T20D is a wireless serial port module
(UART) based on SEMTECH's SX1276 RF chip. It has
multiple
transmission modes, working in the
862MHz~893MHz, (default 868MHz), LoRa spread
spectrum technology, TTL output
，
compatible with
3.3v~5v IO.
SX1276 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.E32-868T20D 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.
E32-868T20D strictly follows design standards of FCC, CE, CCC and meets various RF certification requirements
for exporting.
