I want a header on my board to be reversible. The header has 4 UARTs, 4 power pins (VA,VB,VC,VD), and power (3V3) and PWM for a servo. The functions of most of the signal pins of the header are symmetric, so channels A,B,C,D become D,C,B,A if the polarity is reversed. The only exception is a PWM connection. I'm wondering if having two pins for the PWM signal is going to cause issues. Should I connect these two pins together on both ends or only one end? Or is there a better way to deal with it? The pinout is pictured below.
Thanks in advance
