Denmark's state-run postal service, PostNord, is to end all letter deliveries at the end of 2025, citing a 90% decline in letter volumes since the start of the century. The decision brings to an ...

Arduino UNO, MEGA2560 and NANO are the most common boards, but many others are available. Each has its own specification, which will become of greater importance as a maker’s knowledge increases.

The Board Overview Now, if we look at the Arduino Uno R4 WiFi development board, we can see that it comes with many hardware upgrades over its predecessor. Here is a part marking image of the Arduino ...

The Uno Rev3, is a great beginner board as it's included in many starter kits. It's also complemented with a host of online resources that even without the official Projects Book from Arduino, you ...

The Arduino Nano and Uno are equipped with very similar processors (the chip that essentially serves as the brain of the board). The Nano features an ATmega328, while the Uno sports an ATmega328P.

The powerful Arduino UNO R4 is the latest addition to the iconic Arduino UNO family. It even comes in two versions, so, let's take a look at the UNO R4 Minima and WiFi board. The Arduino UNO R4 has an ...

Features common to Arduino R4 – ‘WiFi’ (€25, below) and ‘Minima’ (€18, right) IO connections are in physically similar positions to Uno R3, and IO remains 5V. USB connector changed to Type-C. 6 – ...

Arduino UNO R4 Minima Both Arduino UNO R4 boards retain hardware compatibility with the UNO form factor and 5V operating voltage meaning you can keep using existing shields. They also add HID support ...

Arduino has launched its next generation of UNO boards, introducing a 32-bit Renesas microcontroller and Espressif ESP32-S3 module, one-click cloud connectivity and plenty of I/O plus a 12×8 red LED ...

Keeping the pinout, voltage and form factor unchanged from the UNO R3 ensures maximum hardware and electrical compatibility with existing shields and projects while allowing the UNO R4 boards to ...
