Questions
How big is the MEASURE POWER AC PCB?
It measures 98.1 × 99.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MEASURE POWER AC use?
260 parts, built around the STM32F103C8T6, CH340C, HLK-5M12 and OP07CSZ. 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 MEASURE POWER AC KiCad files?
From the DONGKHOA/MEASURE-POWER-AC repository on GitHub, at the commit this page was made from: the board is Hardware/MEASURE_POWER_AC/MEASURE_POWER_AC.kicad_pcb and its schematic Hardware/MEASURE_POWER_AC/Connectors.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MEASURE POWER AC design in my own project?
Its repository states no licence, so its author keeps all rights: ask DONGKHOA before reusing the design.
