Questions
How big is the Sensor array PCB?
It measures 80 × 16.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Sensor array use?
29 parts, built around the QRE1113GR and BSS214NW-TP. 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 GR3Y-SCALE/EGB220-A10 repository on GitHub, at the commit this page was made from: the board is hardware/PCB/Sensor_array/Sensor_array.kicad_pcb and its schematic hardware/PCB/Sensor_array/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 GR3Y-SCALE before reusing the design.
