Questions
How big is the Tp2 PCB?
It measures 61.5 × 41.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Tp2 use?
34 parts, built around the LM324. 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 Tp2 KiCad files?
From the fpp3/TeoriaDeCircuitos2 repository on GitHub, at the commit this page was made from: the board is tp2/sources/Circuito/tp2.kicad_pcb and its schematic tp1/sources/tdc2_tp1_ej1/tdc2_tp1_ej1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Tp2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask fpp3 before reusing the design.
