A USB-controlled potentiostat/galvanostat for thin-film battery characterization


AxelMcKenna/AFX-1000
RMX-1000-inspired effects processor for macOS, AU and VST3, built on a shared C++20 engine. Standalone Daisy Seed 3 hardware with two main PCBs and a custom housing is in development.





It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
142 parts, built around the 74AHCT244D, R-78E3.3-0.5, OPA4192ID and BC847. 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.
From the marangisto/ProtoCV repository on GitHub, at the commit this page was made from: the board is ProtoCV.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
