Questions
How big is the Squathero V1 PCB?
It measures 28.7 × 42.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Squathero V1 use?
41 parts, built around the AMS1117-3.3, TP4057, HL2307 and 1N5819WS. 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 Squathero V1 KiCad files?
From the jasonbowman55/PCB_Design repository on GitHub, at the commit this page was made from: the board is squat_hero/squathero_V1/squathero_V1.kicad_pcb and its schematic Learning/1_usb_555timer/USB_555timer/USB_555timer.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Squathero V1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask jasonbowman55 before reusing the design.
