The "Schematic" on the documentation pages are kinda halfway between a block diagram and a schematic (and is just the image of the sticker that is on the actual device). Most M5Stack products have actual schematics posted; I was hoping they would be willing to post the actual schematics for these as well (the part numbers and hookups in the schematics allow us to check datasheets to determine additional information to questions we may have: voltmeter max voltage tolerance, eeprom address changeable?, ammeter fuse "resettable"?, ammeter fuse speed/curve, etc).
