1. Overview
1.1 Introduction
E32-915T30S is a wireless serial port module
(UART) based on SEMTECH's SX1276 RF chip. It has
multiple transmission modes, working in the
900MHz~931MHz, (default 915MHz), LoRa spread
spectrum technology, TTL output, compatible 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 30dBm transmitting power adopt industrial grade crystal oscillators to ensure the stability
and consistency, its precision is lower than the widely adopted 10ppm.E32-915T30S 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.
E32-915T30S strictly follows design standards of FCC, and meets various RF certification requirements for
exporting.
