Hi everyone, i've been slowly modding my WRT54GS router and tonight I decided to do the SD card hack. To be honest i've looked at so many pictures of different versions of this modem i've got in bit of a muddle so hoping someone can clear things up for me.

Here's what I have so far

I "believe"

yellow do gpio4

green clk gpio3

blue d1 gpio5

green clk gpio3

orange gpio4

white gpio7

I seem to have 2 gpio3's? also is there somewhere else I can get 3.3v and GND from as I use the serial connection. Am I missing any other ones?

Save yourself some troubles by measuring the pins you "believe" to be the right ones with a multimeter while toggling the expected gpio between 0 and 1.

decided to take up this mod again, can anyone help me with the correct pins?
