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
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
