Questions
How big is the Analog Sandbox PCB PCB?
It measures 203.2 × 101.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Analog Sandbox PCB use?
104 parts, built around the NE555P and 3362P-1-103LF. 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 Analog Sandbox PCB KiCad files?
From the lbracy/Analog_Sandbox_PCB repository on GitHub, at the commit this page was made from: the board is Analog_Sandbox_PCB/Analog_Sandbox_PCB.kicad_pcb and its schematic Analog_Sandbox_PCB/Analog_Sandbox_PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Analog Sandbox PCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask lbracy before reusing the design.
