I have been working with a pi 3 b+ and a PWR.A53.B power and driver board . Sadly the switch on the power board was damaged and fell of . I couldn’t put the switch together as I lost the small pieces . I tried shorting the 2 terminals but then either one side of the motors work or the raspberry can’t be accessed ie There always seems to be a problem.
I tried buying a new driver board same model online but I couldn’t find it anywhere . Now I am trying to replace the switch with a new one from amazon so I was wondering how do I go about it ? thanks
