As we discussed in my previous column, until a few weeks ago, the Arduino Uno microcontroller development board we’ve all grown to know and love was the R3 (“Revision 3”). This little rascal is ...

Arduino introduces its new module »Uno R4«. It is the successor of the R3 module and contains a Wi-Fi module in the extended version. It is also the first Arduino module with 32-bit microcontroller.

A rduino boards are a popular choice for DIY electronics, but it's not always clear how to get started with building projects ...

Connector to add external battery to real-time clock (RTC) inside Renesas MCU (MCU RTC power pad held to 5V rail on Minima) Secondary (wireless) processor: 240MHz 3.3V dual core 32bit Espressif ...

The Uno board has 14 digital input/output pins – with six that can be used as PWM outputs – and six analogue inputs. Other features include a 16MHz ceramic resonator, USB connection, an ICSP header, ...

Someone has invented a way to add Wi-Fi to a standard Arduino Uno, by proposing a module that drops into the DIL socket normally reserved for the ATmega328 – it will not work with Unos that have a ...

Two new variants of the Arduino Uno development board, the lightweight Uno R4 Minima and the full-fledged Uno R4 WiFi, are each powered by a 32-bit microcontroller. These next-generation Uno boards ...
