It measures 70.7 × 55.5 mm and has 4 copper layers, 1.77 mm thick.
64 parts, built around the ATSAMD51J20A-AU, ESP32-S3-WROOM-1-N4R2, KMR231NGLFS and AP2112K-1.8. 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.
From the malikhubb/Oversoon repository on GitHub, at the commit this page was made from: the board is OverSoon.kicad_pcb and its schematic OverSoon.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask malikhubb before reusing the design.

휘트스톤 브리지(Wheatstone Bridge)는 저항 4개로 두 개의 분압기를 만들고, 두 중간점의 전압 차이로 저항의 균형 여부를 판단하는 회로이다. 이 예제에서는 예제 1의 흐름(회로도 → PCB)에 더해 KiCad에 내장된 SPICE 시뮬레이터(ngspice) 로 회로를 먼저 계산해 보는 방법을 익힌다.
