Product Descriptions

E30-433T20S3 is a wireless serial port module (UART) based on imported SI4438 RF chip, with half duplex, integrated transceiver, transparent transmission mode, patch type, TTL level output, operating frequency range of 425-450.5MHz (default 433MHz), transmission power of 100mw, and air wake-up function (ultra-low power consumption), suitable for various environments. The product has been mass-produced and widely used in various industries.

The module has a software FEC forward error correction algorithm, which has high encoding efficiency and strong error correction capability. In the event of sudden interference, it can actively correct the interfered data packets, greatly improving reliability and transmission distance. Without FEC, this type of packet can only be discarded. The module has data encryption and compression functions. The data transmitted by the module in the air has randomness, and through rigorous encryption and decryption algorithms, data interception becomes meaningless. The data compression function has the potential to reduce transmission time, minimize the probability of interference, and improve reliability and transmission efficiency.

E30-433T20S3 strictly complies with domestic and foreign design specifications such as FCC, CE, ROHS, etc., meets various RF related certifications, and meets export requirements.
