Questions
How big is the Programmable Load PCB?
It measures 97 × 100.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Programmable Load use?
126 parts, built around the INA219AID, AD8628AR, ADS1115 and LM1117-3.3. 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 Programmable Load KiCad files?
From the pommen/Programmable_Load repository on GitHub, at the commit this page was made from: the board is HW/v2/v2.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Programmable Load design in my own project?
Its repository states no licence, so its author keeps all rights: ask pommen before reusing the design.
