1. Overview
1.1 Introduction
E32-900T20D is a wireless serial port module (UART) based on
SEMTECH’s SX1276 RF chip. It has multiple transmission modes,
working in the 862MHz~931MHz, LoRa spread spectrum technology,
TTL output.
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. E32-900T20D 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).
E32-900T20D strictly follows design standards of FCC, CE, CCC and meets various RF certification requirements
for exporting.
