E31-230T17D is a 230M SMD wireless serial port module (UART) with AXSEM AX5243 RF chip imported from Switzerland ,half duplex, transceiver integrated, transparent transmission mode, 225~237.6MHz frequency band (default 230MHz), TTL level output With air wake-up function (ultra low power consumption).
E31-230T17D 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.
