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.

Arduino NANO v3 (ATmega328) or clone; Arduino MEGA (ATmega2560) ... COM1 is often the motherboard serial port even if you don't have any physical port, if you can't see it disapearing when unplugging ...

Options to power the Arduino Nano include USB, VIN, ... still three other ways you can power your Nano: via the USB port, VIN pin, and 5V pin. Connect a cable to the on-board mini-B USB port.

Both the Arduino Nano and Uno can be powered via their integrated USB connectors. This automatically supplies regulated 5V power to the board, allowing you to use any USB-supported power source ...
