Questions
How big is the Sensor array atmega PCB?
It measures 99 × 60 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Sensor array atmega use?
25 parts, built around the ATMEGA328P-AU. 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 atmega KiCad files?
From the hpvdt/falcon_windspeed repository on GitHub, at the commit this page was made from: the board is hardware/sensor_array_atmega/sensor_array_atmega.kicad_pcb and its schematic hardware/sensor_array_atmega/sensor_array_atmega.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sensor array atmega design in my own project?
Its repository states no licence, so its author keeps all rights: ask hpvdt before reusing the design.
