There's an older thread where someone gets one of these Waveshare 3.3 V SD card adapters working: Use SDCard with MicroPython on Raspberry Pi Pico - Raspberry Pi Forums.
User danjperron's contribution in the same thread is particularly helpful: Use SDCard with MicroPython on Raspberry Pi Pico - Raspberry Pi Forums
I applied his approach (and his home-made µSD card adapter) in this post: how to mount SD card to pico filesystem - Raspberry Pi Forums
I repeated that again this evening: first I installed the sdcard library:I hooked up the SD card interface like this on physical pins 14–17 (SCK on GP10, TX on GP11, RX on GP12, CS on GP13).
Then I ran this code:Now I can access the card from the MicroPython REPL:We're only using one of the data lines from your SD card as we're using SPI mode.
