Overview
Sixi2-mega shield is an open-source printed circuit board by MarginallyClever, from the MarginallyClever/sixi-2 repository on GitHub, published under the GPL-2.0 licence. It is a 2-layer board of 87.6 × 53.3 mm with 22 parts on 47 nets, routed with 247 tracks and 0 vias.
It is built around the PN2222A. Its parts include 9 transistors, 6 connectors and 6 switches. It belongs with the robots and motor control boards and the AVR (ATmega, ATtiny) boards of this library.

Motivation
3D printers can print parts for themselves, but they cannot self-assemble. The long goal of the Sixi is to build a machine that can assemble copies of itself.
When 3D printers were closed source, they started at $10k. Makerbot and Prusa changed the game by bringing high quality open source 3D printers down to $2k. Marginally Clever Robots, Ltd. aims to be the Prusa of robot arms.

Notes
The BOM.csv lists all the parts in the kit, most of which are off-the-shelf. Some parts are manufactured.
[LSR] laser cut
[CNC] metal cut on a CNC mill
[3D] 3D printed PLA plastic.All the 3D printable parts were produced on a Prusa MK3S. Parts are carefully designed to have a minimum of support material cleaning. Please see STLs/STLPrintSettings.csv for recommended layer height, speed, color, etc.
The Sixi has no glue because we like operations that can be undone.

Questions
How big is the Sixi2-mega shield PCB?
It measures 87.6 × 53.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Sixi2-mega shield use?
22 parts, built around the PN2222A. 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 Sixi2-mega shield KiCad files?
From the MarginallyClever/sixi-2 repository on GitHub, at the commit this page was made from: the board is sixi2-mega-shield/sixi2-mega-shield.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sixi2-mega shield 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).
