2 Questions about the V4 Shield

Recommended Posts

Hello, 

 

I've recently buy PCB only for making a new display With Pin2DMD (192*64 in this case, so V4 shield only)

But i've 2 mistakes with the board

 

1st : There 8 pins for Resistor Network instead of 6 (V3 Shield) I can buy it, but are they still 220 Ohm  or different value ? 

2nd : I've two type of SDCard Reader, but no one fits on this new board... Can I adapt one on this board ? Or Should I buy another model of Reader ? (And in this case, witch one ? )

Many many thanks for your help ?

Best regards ?

Not bussed  ? So this kind of resistance array is not good ?

And for the Reader, 

Is SDIO and WaveShare are compatibles ? 

Because I can find easyer a SDIO Reader than a real WaveShare, but if we take a look at the pins there are not the same... Depsites sites description told me is equivalent...

LEFT WaveShare - RIGHT SDIO Reader...

So i'm a little lost with the V4 version... 

 

Thanks again for your precious help Lucky1 ?
