These designs were made with KiCad:
CC11xx is a series of RF transceiver ICs from Texas Instruments. The particular parts used by these designs are CC1110 and CC1111, both of which integrate an 8051 microcontroller. The CC1111 additionally has an integrated USB device peripheral.
This repository contains a number of projects which use cc11xx chips (ToorCon 14 Badge, etc.) plus some useful stuff for working with them (KiCad library including schematic symbol and PCB footprints).

Questions
How big is the Turnipschool PCB?
It measures 22.5 × 12 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Turnipschool use?
62 parts, built around the USB2412-DZK and AH1806-W. 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 Turnipschool KiCad files?
From the mossmann/cc11xx repository on GitHub, at the commit this page was made from: the board is turnipschool/turnipschool.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Turnipschool 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).
