1. Product Description
433MHz wireless receiver is an important supporting device in wireless handheld systems. The wireless receiver is based on FSK modulation and adopts efficient forward error correction channel coding technology, which improves the ability of data to resist burst interference and random interference; Provide a transparent data interface that can adapt to any standard or non-standard user protocol and automatically filter out false data generated in the air; Intelligent data control, even for half duplex communication, users do not need to write extra programs, as long as they receive/send data from the interface; It has ultra-high flexibility and reliability.
2. Main features
Wireless receivers are suitable for short-range wireless data transmission.
