1. Overview
1.1 Introduction
E31-433T30D 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.
E31-433T30D strictly abides by FCC, CE, CCC and other domestic and foreign design specifications, meets all RF
related certifications, and meets export requirements.
