Overview
This is simply a breakout that has been optimized for my workflow, not to have a cheap product on amazon.
Features:
Integrated precision 3.3V reference using the LM4040D33 Dual channel DAC using the MCP48FVBXX (8/10/12 bit options are available) Dual 2x4 headers each for SPI0 and SPI1, allowing jumper to a daughterboard and monitor using a logic analyzer Dual 2x2 headers each for I2C0 and I2C1, allowing jumper to a daughterboard and monitor using a logic analyzer On-board reset to factilite putting into BOOTSEL mode without unplugging the USB cable DIP switch to disable on-board VUSB->3.3V converter, to allow powering from a low-noise source Keystone test points and 0.1" header pins for GPIO and ADC

Questions
How big is the Rpi platform r1 PCB?
It measures 98.4 × 98.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Rpi platform r1 use?
55 parts, built around the LM4040D33FTA, MBR120VLSFT1G-TP and TL3305BF260QG. 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 Rpi platform r1 KiCad files?
From the 65roadster/TinyBench-Pico repository on GitHub, at the commit this page was made from: the board is rpi-platform-r1.kicad_pcb and its schematic rpi-platform-r1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Rpi platform r1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask 65roadster before reusing the design.
