E31-230T33D AX5243 UART 8Km Low Frequency High Diffraction 230MHz 33dBm DIP 37*60 mm CE RoHs FCC LoRa Wireless Transmitter

Product Descriptions

E31-230T33D 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). 

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. 

E31-230T33D strictly abides by FCC, CE, CCC and other domestic and foreign design specifications, meets all RF related certifications, and meets export requirements.
