Questions
How big is the MicArray PCB?
It measures 83 × 39 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MicArray use?
87 parts, built around the SN74HC138D and ICS-52000. 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 MicArray KiCad files?
From the dylanzodrow/Aerial_Drone_Tracking repository on GitHub, at the commit this page was made from: the board is Kicad3/MicArray.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the MicArray design in my own project?
Its repository states no licence, so its author keeps all rights: ask dylanzodrow before reusing the design.
