Wide Input Shim


I have some questions regarding the Wide Input Shim:

  • is it possible to combine the Wide Input Shim and the On/Off Shim simultaneously on one pi?
  • using 12 V input, how much current do I have to provide to have the 2 A, 5 V full output?
  • what is the dimension of the 5.5mm OD female adapter inner pin? 2.5 mm or 2.1 mm?

Best wishes,


5V @ 2 A is 10 Watts. 12V @ 0.833 is also 10 watts so you need 0.833 A. Thats not accounting for any lose in the conversion so I’d say at least 1A to play it safe.
I would think, to use both, you would have to feed the +5V output of the Wide input shim to the input of the on off shim. You won’t be able to mount them both onto the GPIO header.


Thank you very much for your help!


Since I do now have the Wide Input Shim at home I can say that the female connector has the dimensions 5.5mm/2.1mm. The pirates may consider adding this information to their description since there are so many different connectors out there.
