An evaluation board for Vangotech V9203 3-phase energy monitor in a Featherwing format. It has been tested with Arduino enabled feathers and should work with any Arduino platform with an SPI bus.
The SPI bus is 3.3v and exposed via the Feather headers and the JST connector on the top for people wishing to use it with non-feather format boards as host processor.
The board can be obtained on:
