This is an Arduino UNO on steriods! All the same functionality plus a whole lot more. This Arduino UNO has a WIFI chip integrated on the board and allows you to easily and quickly start creating IoT devices without needing an additional WIFI module.
Also worth mentioning is that this Arduino UNO has 32MB of memory for you to use! It is more than sufficient to host your own server & websites directly on the Arduino UNO.
The only major additional difference to a normal Arduino UNO is that this WIFI version uses a micro USB adaptor. These micro USB cables are available at Leobot Electronics.
