## Questions & Answers

**Q: Can i use adafruit motor shield for arduino v2.3 with this board?**
A: I don’t see why you couldn’t be able to as long as the 𝐒hield has the shape of an uno. However I had to buy an uno because the processor architecture is different with the WiFi revision 2 because it uses a different chip. The program I wrote was unable to run on the WiFi revision 2 but worked fine on the uno revision 3

**Q: does it support  I2C?**
A: Yes

**Q: What’s the difference between this and the yun rev 2?**
A: I think the revision 2 uses a different processor chip while the revision 1 uses the atmega328 which is the same as the uno

**Q: I got it to connect to my WiFi with a sketch but  I can't get anything from 192.168.240.1 is this the rigth address?**
A: It seems like you are using the previous version of the uno wifi. The uno wifi rev 2 doesn't have a web panel, in order to control the wifi connection you need to use the WIFI NINA library

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Genuine Arduino Board
  

*by M***N on Reviewed in the United Kingdom on 29 March 2022*

Ideal for Arduino projects where you need a Wifi connection.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Cracking bit of kit
  

*by D***C on Reviewed in the United Kingdom on 16 July 2019*

Purchased this to automate fan speeds based on temperature sensor readings. If you've used an Arduino before then this will be easy to use. Wifi module works brilliantly.

### ⭐⭐⭐ 3.0 out of 5 stars







  
  
    It's not just a Uno with wifi
  

*by J***Y on Reviewed in the United Kingdom on 6 June 2020*

I wanted to get into Arduino and had a few projects in mind - one of which would have been helpful to have Wifi so thought I would get this model rather than the basic Uno.  Turns out that it is a very different board and that lots of shields and example code don't work.  If you know what you're doing then it'll be fine but if you are a beginner like me you would be better getting a plain Uno and getting this later.I bought a Uno later to unlock some of the projects I was having problems with and don't regret having this (I've done some interesting bluetooth low energy stuff connecting to a microbit) I was initially frustrated
