[!WARNING] This PCB is a messy prototype that has never been cleaned up, and it may not work at all. It was created for the sole purpose of quickly testing an 8-microphone setup on a very old SensEdu revision, and is published for reference rather than for reproduction.
If you need an 8-microphone version, please contact us and we will help you with it.

Questions
How big is the Ultrasound shield 8mic PCB?
It measures 199 × 200 mm and has 4 copper layers, 1.29 mm thick.
What parts does the Ultrasound shield 8mic use?
183 parts, built around the AD8426ACPZ-R7, DPS310XTSA1, LT1790ACS6-1.25#PBF and IM73A135V01XTSA1. 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 Ultrasound shield 8mic KiCad files?
From the ShiegeChan/SensEdu repository on GitHub, at the commit this page was made from: the board is projects/Ultrasonic_3D_Tracking/pcbs/sensedu-extended-kicad/Ultrasound shield_8mic.kicad_pcb and its schematic pcb/External_Microphone_Connectors.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ultrasound shield 8mic design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
