Arduino created a Renesas RA4M1 microcontroller board in its Nano form-factor. Called Nano R4, it follows the Uno R4, the first Arduino to use the RA4M1. Episode 13 of our podcast CHIIPs is out now, ...

Arduino has shrunk the UNO R4 with the Arduino Nano R4 board equipped with the same 48 MHz Renesas RA4M1 32-bit Arm ...

The term “Charileplexing” is not a familiar one for many electronics hobbyists. Charlieplexing is a technique proposed in early 1995 by Charlie Allen (at Maxim Integrated) for driving a multiplexed ...

What Is Arduino? A microcontroller is a small computer, generally about 1/1000 as powerful as the average laptop, and in this case, with a USB port and a series of pin connections.

The size of the microcontroller generally depends on the amount of pins and flash memory. For beginners, I'd recommend purchasing the Arduino Duemilanove, as it is inexpensive ($30) and very easy ...

Aside from the USB port, you can power your Arduino boards with any regular battery connected to its VIN pin. The supply voltage depends on the board, but the more popular ones use 9V.

Developers, makers and electronic enthusiasts using the SEEED Seeeduino XIAO Arduino microcontroller, may be interested to know that the smallest Arduino compatible board in the Seeeduino Family ...

Microduino actually isn't the smallest Arduino clone on the market. The Femtoduino, boasting the "same power and pin count of an Arduino Uno," measures just 0.81" × 0.6".
