From eLinux.org
Jump to: navigation, search

So you want to use a SD or mmc card with your Didj...

This is the right place to look

Setting Up the Hardware

The Didj doesn't have a SD card slot built in so you will have to manufacture or buy a custom cart adapter.

Here is an example on how you can directly wire a SD cart to your Didj It is better to use a sd breakout board so you can remove the card parts you will need:

  • SD card breakout
  • 3 x 10k ohm resistors
  • 1 x 3k ohm resistor
  • some wire
