Hi Ryan: Many thanks for your suggestions: Sorry for my not clear description, the customer wants to evaluate two designs: 1. If leave the GPIOs floating and set output, they care about the power whether change higher? Since they need to design the product in low power. 2. The other design is if they want GPIOs(4 GPIOs) to connect resistor to ground, can they use only one resistor? Pls. give us more suggestions.
