works at 433MHz, with TTL level output, and is compatible with 3.3V. The module has data encryption function. The
data transmitted by the module in the air is random. Through strict encryption and decryption algorithms, the data
interception is meaningless, the probability of interference is reduced, and the reliability and transmission efficiency are
improved. Besides, it is a low-cost wireless serial transceiver module.
