This integrated board is perfect for wireless applications and is the same size as the original UNO. It is based on the ATmega328 MCU together with the ESP8266 WiFi module. The WiFi element is a self-contained SoC with integrated TCP/IP protocol stack giving you access to a WiFi network. One of the main advantages of this is its support of OTA (Over-the-air) programming.
The Uno is a microcontroller board based on the ATmega328P. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header and a reset button. It contains everything needed to support the microcontroller, simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. You can tinker with your UNO without worrying too much about doing something wrong, worst case scenario you can replace the chip for a few dollars and start over again.
