Questions
How big is the ATM90E36A V1 PCB?
It measures 84.3 × 57.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ATM90E36A V1 use?
80 parts, built around the CH340C, ESP32-WROOM-32D, ATM90E36A-AU-R and AMS1117-3.3. 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 ATM90E36A V1 KiCad files?
From the ClaudioSeda/ATM90EEnergy repository on GitHub, at the commit this page was made from: the board is ATM90E36A/hardware/ATM90E36A_V1.kicad_pcb and its schematic ATM90E36A/hardware/ATM90E36A_V1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ATM90E36A V1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask ClaudioSeda before reusing the design.
