Questions
How big is the Pico adc basic PCB?
It measures 51 × 21 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pico adc basic use?
54 parts, built around the MCP6231U-E/LT, OPA2325ID, ADS1115 and PCA9500D. 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 Pico adc basic KiCad files?
From the shabaz123/adc_board_basic repository on GitHub, at the commit this page was made from: the board is pico_adc_basic.kicad_pcb and its schematic pico_adc_basic.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pico adc basic design in my own project?
Its repository states no licence, so its author keeps all rights: ask shabaz123 before reusing the design.
