Arduino Uno R4 – Minima & WiFi

Arduino Uno R4 – Minima & WiFi

After 12 years, Arduino has released the latest edition of the classic Arduino Uno. Actually, it’s two boards, the Arduino Uno R4 Minima and the Arduino Uno R4 WiFi.

These boards are 5-volt logic devices and are physically compatible with the older Arduino Uno R3 boards, preserving your investment in shields and prototyping equipment. In addition, they offer many new features, several of which we’ll examine today.

Build a Pico “Uno” – Prototyping with the Pico

The Raspberry Pi Pico is a very powerful microcontroller, especially when compared to an Arduino Uno. Yet most of the time we reach for a board to test with, we pick an Uno! This is because the Uno is easier to prototype with.

Well, today we’ll change all that and build three different “Pico Uno” boards that have the power of the RP2040 and the ease of use of an Arduino Uno.
