Boards in 2 GitHub repositories, designed in KiCad, that use the ATM90E36A-AU-R by Microchip Technology (-40℃~+85℃ 0.1% 16.384MHz 2.8V~3.6V 23mA 6000:1 6ppm/℃ 7 Polyphase Energy Metering IC Pulse output、Interrupt control、Fault detection、Built-in temperature sensor、Programmable gain、Built-in reference source、Harmonic analysis、Energy accumulation engine SPI TQFP-48(7x7) Energy Metering ROHS). See how each wires it, with its parts, size, README and files; the ATM90E36A-AU-R’s symbol, footprint and pinout are on its own page.
