While V-USB supports the AVR's internal RC oscillator (only at 12.8 MHz and 16.5 MHz), you'd have to extend this project with runtime oscillator calibration support. This shouldn't be too difficult if ...

USBgpio connects to any modern PC via USB. It has a row of exposed GPIO pins and users can control their states programmatically using Python. Inside the GPIO you will find an Arduino Nano 33 IoT ...

Some of them are connected to native serial ports, and some have USB->RS232 adapters. I am communicating to them via the serial port interface and their /dev/ttyUSB* device nodes.

2) Use it as an extra GPIO Header – for if you’ve run out of pins on the Raspberry Pi, or want to use two add-on board together. You will gain an extra Raspberry Pi header that is pin-for-pin ...
