Here is a part marking image of the Arduino Uno R4 WiFi for better understanding. Here as you can see the Arduino Uno R4 WiFi comes with two microcontrollers, one is the ESP32-S3 from Esperissif for ...

The Arduino Uno is an open-source microcontroller board based on the Microchip ATmega328P microcontroller and developed by Arduino.cc. It was first developed back in 2003 as an affordable ...

I'll be focusing more on I/O and analog based microcontrollers, such as those running Arduino, and using Atmel chips as examples (these are most commonly available, and easy to program).

That link also contains listings of workshops using the Shrimp microcontroller. Since it appears just like an Arduino Uno you can do any of the hundreds of projects for that board.

Renesas’ SVP, Chris Allexandre, said, “We are honored to collaborate with Arduino on their iconic UNO product line. Despite the challenges of this intricate project with a rich legacy, our 5V 32-bit ...

Arduino Uno was one of the most popular microcontroller development boards, thanks to the easy to use Arduino programming environment and the community support. Even though Arduino has released ...
