ManiacalLabs/Super7Seg2The Super 7 Seg kit takes using a 7 Segment display to the extreme! It started as an exercise in "how many 7 segment displays can I drive with a single ATMega328p" and we are quite proud of the result.
Panel2 is an open-source printed circuit board by ManiacalLabs, from the ManiacalLabs/Super7Seg repository on GitHub, published under the MIT licence. It is a 2-layer board of 106.7 × 101.2 mm with 128 parts on 58 nets, routed with 1,896 tracks and 160 vias.
It is built around the ATMEGA328P-PU, 74HC238D and ULN2003A. Its parts include 68 resistors, 24 connectors, 12 ICs and 8 capacitors. It belongs with the AVR (ATmega, ATtiny) boards of this library.

Twelve beautiful, bright, 0.8" tall digits powered and driven by only 3 pins. The simple serial connection (literally just sending text) means you can have a simple to use 7 segment display controlled by anything able to output a serial signal, including but not limited to Arduino, Raspberry Pi, and any normal computer (with a USB to serial cable). If required, there are also basic, easy to use, commands that can be sent allowing direct control over each segment of each digit of the display.
But wait, is twelve digits not enough for you? Fear not! You can chain up to 10 Super 7 Seg displays together and still control all of them from just the same 3 pins! Every bit of text that won't fit on the first display is automatically sent down the line to the next and the next after that.
The Super 7 Seg is a user assembled kit which requires basic through-hole solder skills and comes with the following components:

Interacting with the Super 7 Seg is incredibly easy but we've provided a python module to make it even easier! For more, check out the Super7 Python module doc.

An ATmega328P based automatic voltage stable line switcher: senses three incoming mains lines, picks the one holding steady near 240V, and drives a stepper controlled selector onto it, or to OFF when no line is safe.

It measures 106.7 × 101.2 mm and has 2 copper layers, 1.6 mm thick.
128 parts, built around the ATMEGA328P-PU, 74HC238D and ULN2003A. 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 ManiacalLabs/Super7Seg repository on GitHub, at the commit this page was made from: the board is kicad/panel2.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
