vasectomboy Posted February 8 Share Posted February 8 So I have some Nucleo-F4 shields still to be built for my machines, but I'm not quite understanding what was the correct SD card module meant for that design? The one pictured in Github''s sd_reader.jpg is extremely hard to find from any reputable sources (the only supplier in AliExpress had _RUSTED_ pins on each of the modules), thus I'd like to buy the Waveshare modules instead. Are they interchangeable or should I do a new edit of the PCB instead or what? Link to comment Share on other sites More sharing options...
vasectomboy Posted February 8 Author Share Posted February 8 As an example, would this work without the resistors that are added in the other older module? What is the function of those resistors? https://m.aliexpress.com/item/1005002766855429.html Link to comment Share on other sites More sharing options...

Following the second post in question, would the micro SD card readers work without the 10K pull-up resistors? Link to comment Share on other sites More sharing options...
