The Latest ESP-03 ESP8266 Wifi Module AP & Station Remote Serial Wireless IoT Board was designed based on an integrated chip specifically to fulfil the needs of a new connected world. It can handle all the necessary overhead for communicating with your network. Such as TCP/IP stack and communicating with your 802.11 networks. ESP8266 was designed as a Serial Wifi Wireless Transceiver Module with self-contained SOC and integrated TCP/IP protocol stack. It gives access to any microcontroller to your WiFi network. This Module is capable of either hosting an application or offloading all Wi-Fi networking functions from another application processor. This wireless module is completely addressable over SPI and UART protocols. As a result grants permission to connect your sensors or project directly to it through its GPIO’s.
Each ESP8266 ESP-03module is designed with pre-programmed AT command set firmware. This means that your Arduino device can be simply hooked up and get about as much WiFi-ability as a WiFi Shield offers. The ESP8266 is an extremely cost-effective board with a huge, and ever-growing, community with a full TCP/IP stack and MCU capability. ESP8266 ESP-03 features onboard processing and storage capability that allows it to integrate with the sensors and other application-specific devices through its GPIOs. This is achieved with minimal development up-front and minimal loading during runtime. This module with a high degree of on-chip integration minimizes the need for external circuitry, including the front-end module. Thus achieves minimal PCB area. The ESP8266 also supports APSD for VoIP applications and Bluetooth co-existence interfaces. Using a self-calibrated RF allows it to work under all operating conditions and requires no external RF parts.
