Questions
How big is the SignalFLowLab PCB?
It measures 200 × 200 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SignalFLowLab use?
130 parts, built around the ESP32-S3-WROOM-1-N8, TPS5430DDA, AMS1117-3.3 and K3-2235S-K1. 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 SignalFLowLab KiCad files?
From the Serpant4632/SignalFLowLab repository on GitHub, at the commit this page was made from: the board is KiCad/SignalFlowLab_PCB/SignalFlowLab.kicad_pcb and its schematic KiCad/SignalFlowLab_PCB/East_Street.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SignalFLowLab design in my own project?
Its repository states no licence, so its author keeps all rights: ask Serpant4632 before reusing the design.
