I needed a low-cost test board I could use to demonstrate the issue of both radiated and conducted emissions and chose the Arduino Uno, as it's recently become very popular. The Arduino is an ...

The UNO R4 is powered by the Renesas RA4M1 32-bit microcontroller based on the Arm® Cortex®-M4 core, providing a significant boost in processing power, memory, and functionality. The WiFi version ...

Looking for practical Arduino projects? This guide shows how to control a relay from your smartphone using an Arduino Uno — either via Bluetooth or Wi-Fi.

The UNO R4 is powered by a 32-bit microcontroller, the RA4M1 processor from Renesas, which provides up to 16 times the clock speed, memory, and flash storage compared to the previous 8-bit technology.

Startup code for the Arduino UNO R4 boards (RA4M1 processor) to change from the internal HOCO clock to an external XTAL for the main processor functions. The USB interface remains on the HOCO clock.

Arduino also announced a collaboration agreement with Texas Instruments to use its Sitara AM335x processor. The result is Arduino TRE, the first Arduino board manufactured in the U.S. Thanks to the ...

With no plans to discontinue the popular UNO R3, the UNO R4 will come in two versions – UNO R4 WiFi and UNO R4 Minima. The UNO R4 is powered by the Renesas RA4M1 32-bit microcontroller based on the ...

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 ...
