Overview
Led board is an open-source printed circuit board by HackAveiro, from the HackAveiro/vivacidade repository on GitHub, published under the GPL-2.0 licence. It is a 2-layer board of 43 × 22 mm with 15 parts on 14 nets, routed with 139 tracks and 7 vias.
It is built around the WS2812B. Its parts include 8 capacitors, 2 connectors, 1 resistor and 1 IC.
Main components
1README
README.mdInteractive LED wall
This project is being developed to be installed in a public space in Aveiro that was recovered by a wide group of public and citizens entities. vivacidade.umnovolargo.pt!
The interactive wall has 100 LEDs mounted in jam jars ! Each bottle has an RGB LED ( Neopixel ) and LDR sensor for users to physically interact with the wall. The panel is controlled by an Arduino which uses a radio link to communicate with a gateway situated a few hundred meters away and connects the system to the Internet. Because the place has no available electricity or Internet access it's powered by solar panels.
Users can interact with the system through the Web App: vivacidade-ledmatrixcontroller!

ADC_BOARD!
The system have 10 of this boards to connect all the 100 LED. The ADC board also have ADC chips that convert the LDR light sensors readings. The ADC chips are connected to the Arduino main board via a SPI bus.

Questions
How big is the Led board PCB?
It measures 43 × 22 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Led board use?
15 parts, built around the WS2812B. 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 Led board KiCad files?
From the HackAveiro/vivacidade repository on GitHub, at the commit this page was made from: the board is led_board/board.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Led board design in my own project?
Its repository publishes it under the GPL-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
