Questions
How big is the ADC 16bit board v0r0 PCB?
It measures 65 × 56 mm and has 4 copper layers, 1.6 mm thick.
What parts does the ADC 16bit board v0r0 use?
53 parts, built around the INA126U and AP7380-33W5. 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 ADC 16bit board v0r0 KiCad files?
From the aindustriosa/UnderWaterComms repository on GitHub, at the commit this page was made from: the board is HW/Rpi_Hat/ADC_16bit_board_v0r0.kicad_pcb and its schematic HW/Rpi_Hat/ADC_16bit_board_v0r0.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ADC 16bit board v0r0 design in my own project?
Its repository states no licence, so its author keeps all rights: ask aindustriosa before reusing the design.
