Questions
How big is the TRIVISION sensor board PCB?
It measures 61 × 89.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the TRIVISION sensor board use?
23 parts, built around the ESP32-S3-WROOM-1-N8, MAX30102, AMS1117 and MPU-6050. 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 TRIVISION sensor board KiCad files?
From the include-stdioH/TriVision-Smart-Driver-Monitoring-Board repository on GitHub, at the commit this page was made from: the board is TRIVISION-sensor board.kicad_pcb and its schematic TRIVISION-sensor board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the TRIVISION sensor board design in my own project?
Its repository states no licence, so its author keeps all rights: ask include-stdioH before reusing the design.
