Questions
How big is the Woggle bottom PCB?
It measures 20 × 30 mm and has 2 copper layers, 0.8 mm thick.
What parts does the Woggle bottom use?
38 parts, built around the TSV6191ILT, TPS60400DBV, BAT54GW and MMDT3904. 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 Woggle bottom KiCad files?
From the smrl/wogglebug repository on GitHub, at the commit this page was made from: the board is woggle_bottom.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Woggle bottom design in my own project?
Its repository states no licence, so its author keeps all rights: ask smrl before reusing the design.
