Works fine, worth the money.

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.

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.

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!

Excellent piece of kit will work well

Ordered this following years with the R3. Wow what an improvement. So many new features, and loads of examples in the program. The ESP32 addition opens up so many possibilities - better than a straight ESP32

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.

Ska styra bevattning i växthus. Snabb leverans och bra pris.

Geweldige Uno R4

予想していた通りの品物でした。

Ich nutze den Arduino UNO R4 WiFi seit einigen Wochen für diverse Smart-Home- und IoT-Projekte und bin absolut begeistert vom Leistungssprung im Vergleich zum klassischen R3. Das Board kombiniert den gewohnten Formfaktor perfekt mit moderner 32-Bit-ARM-Leistung und nahtloser Funkkonnektivität. Besonders positiv fällt die hohe Rechenpower des ARM Cortex-M4 auf, die selbst anspruchsvolle Aufgaben mühelos bewältigt. Die Einbindung von WLAN und Bluetooth über das ESP32-Modul funktioniert in der Arduino IDE dank guter Bibliotheken gewohnt einfach; erste Datenströme in die Cloud standen bei mir nach wenigen Minuten. Ein echtes Highlight ist die integrierte 12x8-LED-Matrix, die sich ideal für schnelle Statusanzeigen ohne zusätzliche Verkabelung eignet. Ein kleiner Kritikpunkt betrifft die Kompatibilität: Manche sehr alten Drittanbieter-Bibliotheken des R3 laufen aufgrund der neuen Architektur noch nicht auf Anhieb und erfordern manuelle Anpassung im Code. Trotzdem ist der UNO R4 WiFi das derzeit beste Board für zukunftssichere IoT- und Automatisierungsprojekte. Sowohl für ambitionierte Einsteiger als auch für erfahrene Maker ist das Board jeden Cent wert – eine uneingeschränkte Kaufempfehlung!

Funciona!
