1 Overview

1.1 Introduction

E31-433T30S is a 433M SMD type wireless serial port
module (UART) imported from Switzerland AXSEM AX5243
RF chip, 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 software FEC feature, 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 capabilities. 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.
E31-433T30S strictly abides by FCC, CE, CCC and other domestic and foreign design specifications, meets all RF
related certifications, and meets export requirements.
