Questions
How big is the Power PCB?
It measures 90 × 40 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Power use?
93 parts, built around the DRV8825PWP, ADS1115IDGS, MCP4728-E/UN and 74HC595. 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 Power KiCad files?
From the nodevuser197/astobot-power repository on GitHub, at the commit this page was made from: the board is power.kicad_pcb and its schematic Drv8825.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Power design in my own project?
Its repository states no licence, so its author keeps all rights: ask nodevuser197 before reusing the design.
