1. Overview
1.1 Introduction
E31-433T27D is a 433M DIP wireless serial port module
(UART) with AXSEM AX5243 RF chip imported from
Switzerland, half duplex, transceiver integrated, transparent
transmission mode,425~450.5MHz frequency band (default
433MHz), TTL level output with air wake-up function (ultra low
power consumption).
The module has a FEC forward error correction algorithm,
which has high coding efficiency and strong error correction
capability. In the case of sudden interference, it can actively
correct the interfered data packets, greatly improving reliability and transmission distance. In the absence of FEC, such
packets can only be discarded. The module has data encryption and compression function. The data transmitted by the
module in the air is random, and the data interception is meaningless through strict encryption and decryption algorithms.
The data compression function has the probability of reducing the transmission time, reducing the probability of
interference, improving reliability and transmission efficiency.
E31-433T27D strictly abides by FCC, CE and other domestic and foreign design specifications, meets all RF related
certifications, and meets export requirements.
