Questions
How big is the Blindo PCB?
It measures 97 × 78 mm and has 4 copper layers, 1.61 mm thick.
What parts does the Blindo use?
117 parts, built around the TPS61040DBV, TP4056, AO3400A and B5819W. 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 Blindo KiCad files?
From the STB1019/BLINDO2.0 repository on GitHub, at the commit this page was made from: the board is hardware/board/blindo.kicad_pcb and its schematic hardware/board/analog_filter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Blindo design in my own project?
Its repository states no licence, so its author keeps all rights: ask STB1019 before reusing the design.
