This was a great price for a genuine Arduino board. The board is a great 1st time board as it not only has WiFi and Bluetooth but also has two processors that can be utilised separately if you choose to not use Bluetooth and WiFi. The onboard LEDs make playing with the board quick and fun for beginners. There are so many features on board. The only word of caution is the max amount of amps on the pins has dropped considerably so bigger resistors will be needed, this is important as sketches for the UNO r3 work with 5v and 20 milli amps.This board has maximum 8 milliamps. And the esp32 chip uses only 3.3v. So you just need to check before turning on your projects. Great board though!So always recheck before turning on your projects.

Arduino Uno. Hours of fun making stuff work. I bought this one as it has WiFi. The only snag is that I can’t think why I’d need the WiFi option. I’m sure I’ll think of something.Arduinos are great!

The latest revision of the Arduino Uno has a lot more to offer that its predecessors. Having said that, the design team have have worked to maximise compatibility so this new updated microprocessor board should drop straight in to any existing project.The build quality is very high. The device is fast enough and has capacity to meet a very wide range of requirements.

Excellent piece of kit will work well

My son bought the R4 to help with the microcontrollers unit in his BTEC engineering course. It was just a few quid more than the R3, but is newer, has better features, and importantly it has a USB C interface which was essential to connect with a Mac M1 without an expensive adapter. I bought this with a cheap electronics accessory kit and within days we were building circuits and programming. I did consider the Arduino starter kit but this was far cheaper, and all the resources to learn are online. It’s a great way to learn about coding.

The Arduino UNO R4 WiFi is a great board to start getting into WiFi connectivity and IoT. It's really valuable for beginner projects and is a fun learning tool. It's about the same size as the pervious boards (R3, Leonardo).

The latest Arduino packed with new features such as LED matrix display Bluetooth and WFI
