Overview
Motherboard is an open-source printed circuit board by LiamAlbertVT, from the LiamAlbertVT/Phased_Array_Microphonics_Hardware repository on GitHub. It is a 4-layer board of 166.3 × 148.3 mm with 126 parts on 149 nets, routed with 672 tracks and 50 vias.
It is built around the NE5532, NC3FAAH and JS102011SAQN. Its parts include 57 resistors, 32 capacitors, 18 ICs, 6 transistors and 4 connectors. It belongs with the computers and single-board computers boards and the RP2040 boards of this library.

README.mdRecent Updates
- Slight schematic revisions for logical consistency.
- Added design documentation.
TODO (Upcoming Commits)
- Next semester...
Future Plans
- Enable communication with Raspberry Pi Pico.
- Will eventually add embedded directory to this repo with sample code.
- Revise schematic upon review (likely necessary--this is my first major PCB design).

Questions
How big is the Motherboard PCB?
It measures 166.3 × 148.3 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Motherboard use?
126 parts, built around the NE5532, NC3FAAH and JS102011SAQN. 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 Motherboard KiCad files?
From the LiamAlbertVT/Phased_Array_Microphonics_Hardware repository on GitHub, at the commit this page was made from: the board is Motherboard/Motherboard.kicad_pcb and its schematic Motherboard/Motherboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Motherboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask LiamAlbertVT before reusing the design.
