The stock Arduino Mini USB Host Shield uses 3.3V from Arduino Mini to power up the USB device. Usually this is not enough. Clone boards removed a VBUS jumper so there is no voltage selection, cut the ...

The board is built around an ATtiny3217 and has almost all of the Nano’s features, like a USB port, reset button, built-in LEDs, 5 V regulator, and preloaded bootloader.

Although a “CommsLink” module providing an RS-232 port was available back in the day, it’s become hard to find, inspiring [James] to design a completely new module based on an Arduino Nano.

It's like a shrunken version of the Arduino Leonardo as it features the same ATmega32U4 microcontroller, micro-USB port, and pinouts. It also operates at 5V and requires an external supply of 7 to ...

Logitech's nano receiver has always impressed on-the-go users due to its tiny dimensions (it protrudes by roughly 8mm), and would-be competitors are only just catching up.

To build an FM receiver, developers can use highly integrated chips, such as the TEA5767 from NXP. Here we describe an FM receiver with a frequency range of 76 to 108 MHz and 2 x 3 W stereo sound ...
