From the project
A small, open hardware DMM
KiCad 10, 60 x 50 mm, two layers. Eight I2C-selected gains, buffered half-supply reference, 3.3 V or 5 V analog supply.
Open AD8237DevBoard.kicadpro. Nick's edited PCB is the layout source. Rev C replaces U2 and adds nine resistors. Existing placements are retained except C10, moved slightly to clear the larger mux. The pre-change design is in archive/pre-eight-gain/`.
