In addition to the Wi-Fi interface, the small ESP03 board includes even a programmable microcontroller, thanks to which we could create this demoboard, that enables the creation of wireless applications, in an even easier way and with a limited amount of components. With this board, it is as if having a ready-to-use microcontroller with an integrated Wi-Fi. Not bad… Isn’t it?!

As hinted before, the module is a completely autonomous one, however it is needed to access it via PC, in order to program it; therefore we included an USB/Serial Converter that enables the download of the program to be executed into the ESP8266 module’s flash memory.

The demoboard we propose in this article includes the essentials needed in order to create simple applications, that is to say the USB/Serial Converter and other few components required for the functioning. Among these we will find a voltage stabilizer, some strip connectors and some buttons that simplify the module’s management.
