Questions
How big is the Sensor Array PCB?
It measures 41.1 × 62.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Sensor Array use?
15 parts, built around the SN74LVC2T45DCURE4. 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 Sensor Array KiCad files?
From the qtsohg/pico_sensor_array repository on GitHub, at the commit this page was made from: the board is hw/Sensor Array.kicad_pcb and its schematic hw/Sensor Array.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sensor Array design in my own project?
Its repository states no licence, so its author keeps all rights: ask qtsohg before reusing the design.
