Measuring and test-tools, various prototypes from a single unit volume, create a PCB and its manufacturing data
The hardware review will cover everything from schematic, footprints, signal interconnection, signal and power integrity, to rules for a successful EMC.
I have solutions! Your design will be checked and all point of your concern will be analysed. My own points will be highligthed and discussed. Your issues + my review = leap-frog into a successful design
