WS8555DLS is a wireless serial module (UART) based on TI's CC1310F128RGZR (built-in dual-core ARM) radio-frequency chip, which can work in the 431-446.5 MHz frequency band (default 433MHz), GFSK modulation, TTL level output, and 3.3V IO port voltage; the product adopts a 24MHz industrial grade crystal to ensure its industrial stability. The product adopts 24MHz industrial grade crystal to ensure its industrialization and stability.

The module has data encryption and compression function, the data transmitted by the module in the air is random, through the strict encryption and decryption algorithms, the data interception loses its significance. The data compression function has the probability to reduce the transmission time, reduce the probability of interference, improve reliability and transmission efficiency. The factory has built-in low-power multi-function wireless serial port program.
