No, it's just on the power supply for the brick.
Numbering of pins on the brick, as it sits moounted in the module, start at 1 at the top.
Last two pins at the bottom are 12 & 13.
I use a ceramic 10u which is perfect. If you have an electrolytic check voltages for orientation.
(I forget, but if you get stuck I'll check)
as far as I can work out, it's the brick that generates the noise, and this gets out into the analog circuitry of the module.
