Questions
How big is the 24 channel esp32 energy meter PCB?
It measures 270 × 56 mm and has 4 copper layers, 1.6 mm thick.
What parts does the 24 channel esp32 energy meter use?
352 parts, built around the TCA9534PW, LMR14020SDDA, ATM90E36A-AU and SJ2-35813B-SMT-TR. 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 24 channel esp32 energy meter KiCad files?
From the overallcoma/project-grayskull repository on GitHub, at the commit this page was made from: the board is Hardware/24CHv1.0/24_channel_esp32_energy_meter.kicad_pcb and its schematic Hardware/24CHv1.0/24_channel_esp32_energy_meter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 24 channel esp32 energy meter design in my own project?
Its repository states no licence, so its author keeps all rights: ask overallcoma before reusing the design.
