A wireless module (RF module) refers to a module product that achieves data transmission through radio technology. The module integrates high-frequency components and has conventional interfaces (such as serial ports, SPI, digital signals, etc.), allowing users to develop wireless products without needing to master high-frequency knowledge or purchase expensive RF instruments, significantly accelerating the product mass production speed. The Zhenhao Micro TX8855S is an ASK transmission module operating at 315MHz/433.92MHz. This module features high power (13dBm) and low power consumption (<18mA). The module uses a highly integrated VI8855B chip design that provides stable and reliable performance.
