Smart Meter (ATM90E36 + ESP32)
« on: October 03, 2026, 01:35:25 am »
Hi.

I'm currently working on a three-phase smart meter based on the ATM90E36 metering IC.
You can access all files including schematics and gerber in this repository: https://github.com/hupfer21/Smart-Meter

So far, I've finished the PCB design and have already sent it to JLCPCB for fabrication. I haven't received the boards yet, so I haven't been able to test the hardware.

This is the first board I've sent for professional fabrication and I'd appreciate any feedback on the PCB layout.

Thanks!  :)

Great work, hupfer21. I hope it works good. tell me what happens and the problems you face while testing it. I dont know but I see ground polygon in the AC side is it correct to make polygon in the AC side?!

Okay, I have experience in designing AC meter.
So I will check your design and support you.
