SD card extension #

For convenience a SD extension cable can be used to place the card in a better accessible way. A 25 cm cable is recommend.

You can use both types of cables:

  • microSD card – microSD card
  • microSD card – SD card

Cable modification #

Out-of-the box the cable is not working because of the resistor between VDD (3.3 V) and CLK. The reason for that is unclear.

It is necessary to remove this resistor.
