Sound Camera
Project created in KiCad.
An array of digital MEMS microphones connected to a single clock source.
It contains the following:
- A 2 row, 40-pin 100mil spacing connection header.
- A major array that consists of 16 microphones spaced equally across the PCB.
- Two minor arrays of 9 microphones that make up the 'lower left' and 'upper right' quadrants of the major array.
- A temperature and pressure sensor with clock selection jumper resistors.
- An ultra-sonic speaker and amp.
- An option header to allow multiple arrays to be ganged together on the same ribbon cable.

Questions
How big is the USCAM PCB?
It measures 120 × 120 mm and has 4 copper layers, 1.57 mm thick.
What parts does the USCAM use?
77 parts, built around the MPL115A1T1, SPH0641LU4H-1, CPC1025N and BC337. 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 USCAM KiCad files?
From the LKAPBx/sonicCam repository on GitHub, at the commit this page was made from: the board is USCAM/USCAM/USCAM.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the USCAM design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
