Questions
How big is the River sampler PCB?
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the River sampler use?
99 parts, built around the ATMEGA328P-PU, LM2596S-12, LM2596S-5.0 and TIP120. 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 River sampler KiCad files?
From the Aquaflowies/Rotatory-Distribution-System repository on GitHub, at the commit this page was made from: the board is river_sampler_pcb/river_sampler.kicad_pcb and its schematic river_sampler_pcb/5v_relay.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the River sampler design in my own project?
Its repository states no licence, so its author keeps all rights: ask Aquaflowies before reusing the design.
