Overview
CacheMakerUno is an open-source printed circuit board by UserHackable, from the UserHackable/Cache_Makers_Uno repository on GitHub. It is a 2-layer board of 55.9 × 55.9 mm with 58 parts on 43 nets, routed with 259 tracks and 5 vias.
Its parts include 11 resistors, 6 capacitors, 5 switches, 3 diodes and 2 ICs. It belongs with the AVR (ATmega, ATtiny) boards of this library.
README
README.mdThe Cache Makers Uno project
I created this board in the hopes of using it to teach a group of kids in the Cache Makers 4H program.
The build met with mixed success. The board has a large number of solder points to solder in. The older students with a little more hand eye coordination and practice with soldering did ok, the Younger students struggled quite a bit more. The board, when completed does provide a functional Arduino Uno compatible device, with some extras for convenience when playing around beginning arduino programming.
For the next session, I used the YourDuino RoboRED which I am a fan of.

Questions
How big is the CacheMakerUno PCB?
It measures 55.9 × 55.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the CacheMakerUno use?
58 parts. 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 CacheMakerUno KiCad files?
From the UserHackable/Cache_Makers_Uno repository on GitHub, at the commit this page was made from: the board is KiCad/CacheMakerUno/CacheMakerUno.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the CacheMakerUno design in my own project?
Its repository states no licence, so its author keeps all rights: ask UserHackable before reusing the design.
