Questions

How big is the SensorBoard PCB?

It measures 99.1 × 34.3 mm and has 2 copper layers, 1.6 mm thick.

What parts does the SensorBoard use?

34 parts, built around the TCRT5000. 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 SensorBoard KiCad files?

From the r3dpath/ENMT-LFR repository on GitHub, at the commit this page was made from: the board is PCB/SensorBoard/SensorBoard.kicad_pcb and its schematic PCB/MainBoard/MainBoard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the SensorBoard design in my own project?

Its repository states no licence, so its author keeps all rights: ask r3dpath before reusing the design.
