Questions
How big is the Toad2 PCB?
It measures 121.6 × 107 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Toad2 use?
226 parts, built around the AD633JR. 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 Toad2 KiCad files?
From the microresearch/allcolours repository on GitHub, at the commit this page was made from: the board is TOAD/FINAL_FINAL/toad2.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Toad2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask microresearch before reusing the design.
