Overview
SmallEncoder is an open-source printed circuit board by DDeGonge, from the DDeGonge/OS-ARM repository on GitHub, published under the MIT licence. It is a 2-layer board of 25 × 25 mm with 17 parts on 34 nets, routed with 149 tracks and 13 vias.
It is built around the ATSAMD21E15B-AU, KMZ49 and AP2112K-3.3, with the KMR243G LFG among its other parts. Its parts include 5 capacitors, 3 ICs, 3 connectors, 2 resistors and 1 switch. It belongs with the SAM D and SAM boards of this library.

README
README.mdOS-ARM
An open-sourced, low cost, high performance 3D printed 6-axis robotic arm. The main goals of this project are
- Smooth, repeatable motion
- ~1kg payload
- ~500mm range
- Low cost (<$500 in materials)
- Easy to reproduce (only requiring an FDM printer and basic hand tools)
- Beautiful
- Easy to control
This arm is not industrial and it will not be fast, but that is not my goal. But it will hopefully be a very nice looking arm fully capable of 6dof motion, cheap enough to keep it accessable but capable enough to actually do something (aka carry more than a 50g payload). This is not your typical RC servo arm. It's gonna be epic.
Developemnt will likely take multiple years. This repo will be a work in progress until stated otherwise. Use these files at your own risk!

Questions
How big is the SmallEncoder PCB?
It measures 25 × 25 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SmallEncoder use?
17 parts, built around the ATSAMD21E15B-AU, KMZ49, AP2112K-3.3 and KMR243G LFG. 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 SmallEncoder KiCad files?
From the DDeGonge/OS-ARM repository on GitHub, at the commit this page was made from: the board is EncoderSmall/pcb/SmallEncoder/SmallEncoder.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the SmallEncoder design in my own project?
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).

This is an LED controller for the lights that came with my In-Win A1 Mini-ITX Tower. It came with a simple 12V RGB LED strip, rather than the now-standard WS2812 addressable LED strips that are so common in today's PCs.
