A PCB for an Arduino Nano controlled WS2812B (16x16 LEDs).
NanoLED PCB is an open-source printed circuit board by madmunki, from the madmunki/NanoLED_PCB repository on GitHub. It is a 2-layer board of 50 × 60.1 mm with 11 parts on 30 nets, routed with 60 tracks and 12 vias.
Its parts include 1 capacitor and 1 resistor. It belongs with the AVR (ATmega, ATtiny) boards of this library.
A PCB for an Arduino Nano controlled WS2812B (16x16 LEDs).
The PCB is safe for up to 5A, if you plan to use more than 5A, add a solder layer or wire on back bridging the +5v pin on the barrel, and the cap.

It measures 50 × 60.1 mm and has 2 copper layers, 1.6 mm thick.
11 parts. 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.
From the madmunki/NanoLED_PCB repository on GitHub, at the commit this page was made from: the board is NanoLED_PCB.kicad_pcb and its schematic NanoLED_PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask madmunki before reusing the design.
