needavirus Posted October 14, 2019 Share Posted October 14, 2019 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 ?

Content Provider lucky1 Posted October 14, 2019 Content Provider Share Posted October 14, 2019 It is still 220 Ohm isolated NOT bussed ! Search for Waveshare Micro SD storage board. Link to comment Share on other sites More sharing options...
needavirus Posted October 17, 2019 Author Share Posted October 17, 2019 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 ? Link to comment Share on other sites More sharing options...
