概要
Syntiant社製のデジタル出力MEMSマイクSPH0641LU4H-1を2.54mmピッチへ変換する基板です。
可聴音から超音波(100Hz～80kHz)までの幅広い帯域を高感度にセンシングすることが可能です。
超音波センサや超音波通信などに使用可能です。
マイク穴は基板裏面の丸印部分です。
電源電圧1.62V~3.6V、PDMデジタル出力
セレクトピンをプルアップする場合はR2、プルダウンする場合はR1にチップ抵抗を取り付けてください。
※接続先がDFSDMやI2S、SPI通信等のPDMマスタに対応している必要があります。

Questions
How big is the SPH0641LU PCB?
It measures 20 × 15 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SPH0641LU use?
7 parts, built around the SPH0641LU4H-1. 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 SPH0641LU KiCad files?
From the meerstern/SPH0641LU repository on GitHub, at the commit this page was made from: the board is SPH0641LU.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the SPH0641LU design in my own project?
Its repository states no licence, so its author keeps all rights: ask meerstern before reusing the design.
