Portable Raspberry Pi Zero based computer with a Hyperpixel display
Rpi ibex hyperdisplay is an open-source printed circuit board by jovan3, from the jovan3/rpi-ibex-hyperpixel repository on GitHub, published under the GPL-3.0 licence. It is a 2-layer board of 99.1 × 113.5 mm with 66 parts on 58 nets, routed with 1,048 tracks and 57 vias.
It is built around the ATMEGA328PB-AU. Its parts include 3 capacitors, 3 connectors, 1 IC and 1 crystal. It belongs with the AVR (ATmega, ATtiny) boards of this library.
RPi Ibex is a Raspberry Pi Zero based portable computer. The goal of the project is to provide a way to use Raspberry Pi Zero as a portable computer using parts that are available, cheap and relatively easy to solder (no exotic keyboard controller chips required).
This repository contains Kicad project files for the PCB. The keyboard is just simple push buttons soldered directly on the board. The keyboard controller is an Atmega 328P.

The 62 most common of 66 parts.
It measures 99.1 × 113.5 mm and has 2 copper layers, 1.6 mm thick.
66 parts, built around the ATMEGA328PB-AU. 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 jovan3/rpi-ibex-hyperpixel repository on GitHub, at the commit this page was made from: the board is rpi-ibex-hyperdisplay.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
