Hi,

1. In the example at https://docs.espressif.com/projects/arduino-esp32/en/latest/api/sdmmc.html authors used GPIO43 2times. D2 is GPIO 41 and D3 is GPIO42. Please correct.
2. I'm using a board from Waveshare. Speed is about 370 kB/s. On a ESP32-S3 I got about 1,9 MB/s. Any idea what may be wrong?

Bye, Jürgen
