pre June 2020 PDM15 Input upgrade?
Does anyone know is a pre June 2020 PDM15 be upgraded to have pull down resistors ?
Without them I am having to put additional external components into my wiring that I'd rather not do.
I've been looking at making a simple PCB with grounded 10K resistors for all inputs. Don't supposes anyone has done this already and might share a PCB design?
