Have a sensor project in mind?  LinkSprite Smartworld Solar Panel Sensor Kit provides the solar panel, Li-ion battery to power your Arduino compatible project. The smartworld board has Arduino compatible headers and also an ATMEGA328 with Arduino bootloader. To load the Arduino program, just use a FDTI USB progammer adaptor (http://store.cutedigi.com/breakout-board-for-ft232rl-usb-to-ttl-5v/) to connect to the smartworld board and in Arduino IDE, select the board type as 'Arduino Duemilanover'.  
+
ESP8266 offers a complete and self-contained Wi-Fi networking solution, allowing it to either host the application or to offload all Wi-Fi networking functions from another application processor.
  
−
The smartworld board also has sockets for Xbee module and NRF24L01 so that we can easily add wireless connections. The board also has RTC chip and micro SD card socket on board. Just add a cell battery and we can run the project.
+
When ESP8266 hosts the application, and when it is the only application processor in the device, it is able to boot up directly from an external flash. It has integrated cache to improve the performance of the system in such applications, and to minimize the memory requirements.

Alternately, serving as a Wi-Fi adapter, wireless internet access can be added to any microcontroller-based design with simple connectivity through UART interface or the CPU AHB bridge interface.
  
−
+
ESP8266 on-board processing and storage capabilities allow it to be integrated with the sensors and other application specific devices through its GPIOs with minimal development up-front and minimal loading during runtime. With its high degree of on-chip integration, which includes the antenna switch balun, power management converters, it requires minimal external circuitry, and the entire solution, including front-end module, is designed to occupy minimal PCB area.
