1. Overview
1.1 Introduction
E31-433T17S is a 433M SMD wireless serial port
module (UART) with AXSEM AX5243 RF chip imported
from Switzerland, half duplex, transceiver integrated,
transparent
transmission mode, 425~450.5M H z
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 meaningle ss 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.
E31-433T17S strictly abides by FCC, CE, CCC and other domestic and foreign design specifications, meets all RF
related certifications, and meets export requirements.
