Questions

How big is the CoarseSunSensor2.0 PCB?

It measures 45.4 × 14.2 mm and has 2 copper layers, 1.6 mm thick.

What parts does the CoarseSunSensor2.0 use?

24 parts, built around the ADS1115IDGSR and VEMD6060X01. 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 CoarseSunSensor2.0 KiCad files?

From the spacelab-ufsc/sun-sensor2 repository on GitHub, at the commit this page was made from: the board is CoarseSunSensor2.0/CoarseSunSensor2.0.kicad_pcb and its schematic CoarseSunSensor2.0/16bit_I2C_ADC.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the CoarseSunSensor2.0 design in my own project?

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