5v to 12v, microSD PCB and components

[Droopy22]

Hi,

Does anyone tried to use a 5DC>12DC to power BW (or similar) screen?

Does anyone know where to find a microSD PCB ?
Something like that but shorter and without the reader/sniffer option

3rd and last question about audio low-pass filter.
I took a look to a local wensite (before i go) and it's asked a voltage for capacitor, i know i need 100µF electrolitic and 0.033µF ceramic.... but i ve no idea about a variable audio voltage.
What do i have to choose?

Thanks
And happy new year

I dont think that will work because its a step down module where as you would need a step up module to go from 5v to 12v.

In regards to the micro sd pcb is this what your looking for?

Gonna take a look for step up dc, but in details or says 12v output, that i hoped it was good
For the micro sd i m looking for the card side, i think i found it, waiting for a seller answer
