Overview
NanoDIP is an open-source printed circuit board by profdc9, from the profdc9/NanoDIP repository on GitHub. It is a 2-layer board of 71.1 × 23.9 mm with 14 parts on 31 nets, routed with 508 tracks and 59 vias.
It is built around the ATMEGA328P-PU. Its parts include 7 capacitors, 2 ICs, 1 resistor, 1 diode and 1 switch. It belongs with the AVR (ATmega, ATtiny) boards of this library.
Main components

README.mdNano-like PCB using ATMEGA328P
Because of the 2021 chip shortage, any chip, especially SMT, is not available. However, some ATMEGA328Ps can still be had or removed from older devices such as Arduino Uno.
I made a simple PCB that has the Arduino Nano pinout that takes a ATMEGA328P. It connects to a serial port TTL device, using the DTR line for reset, and can be programmed using the Arduino IDE. A cheap serial TTL converter is a CP2102 or CP2104 device.
ADC6 and ADC7 are not available because they are not exposed on the ATMEGA328P.

Questions
How big is the NanoDIP PCB?
It measures 71.1 × 23.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the NanoDIP use?
14 parts, built around the ATMEGA328P-PU. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the NanoDIP KiCad files?
From the profdc9/NanoDIP repository on GitHub, at the commit this page was made from: the board is NanoDIP.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the NanoDIP design in my own project?
Its repository states no licence, so its author keeps all rights: ask profdc9 before reusing the design.
