Questions

How big is the Vclfo10 PCB?

It measures 76 × 100 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Vclfo10 use?

139 parts, built around the LM358, TL072 and BC547. 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 Vclfo10 KiCad files?

From the EchelonForce/vclfo10 repository on GitHub, at the commit this page was made from: the board is vclfo10_v1/VCLFO10.kicad_pcb and its schematic vclfo10_v1/VCLFO10.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Vclfo10 design in my own project?

Its repository states no licence, so its author keeps all rights: ask EchelonForce before reusing the design.
