HC-22 serial ESP8266, wifi module, replace the Bluetooth wireless
HC-22 is the Department of Science and Technology launched a new order of the fourth generation of embedded Simple -WiFi module products.
Simple -WiFi UART interface is based on compliance with WiFi wireless networking standard embedded modules, built-in wireless networking protocol IEEE802.11 protocol stack and TCP / IP protocol stack, enables users to convert serial data between the wireless network. Through UART-WiFi module, the traditional serial devices can easily access the wireless network.
High-performance wireless module selection ESP8266 SOC, is a complete and self-contained WIFI network solutions that can run independently, can also be mounted as a Slave run on other Host.
ESP8266 when the device is mounted as the only application and an application processor, can be started directly from the external flash memory. Built-in cache memory will help improve system performance and reduce memory requirements.
Another is, wireless Internet access WiFi adapter undertake the task, you can add it to any microcontroller-based design, the connection is simple, simply by SPI / SDIO interface or central processor AHB bridge interface can be.
Processing and storage capacity on ESP8266 powerful piece, it can be integrated via the GPIO port sensors and other applications specific equipment to achieve the lowest pre-development and operation occupy minimal system resources.
ESP8266 highly integrated within the chip, including the antenna switch balun and power management converter, so with minimal external circuitry, and the entire solution, including the front-end module, including in the design of the PCB occupied space to a minimum.
The system is equipped with ESP8266 manifested leading features are: energy VoIP quickly switch between the sleep / wake pattern, with low-power operation of an adaptive radio bias, front-end signal processing functions, troubleshooting and radio systems coexist characteristics of eliminate cellular / Bluetooth / DDR / LVDS / LCD interference
