so this was a the design that I used a while ago for my video on
how to make this transcend wifi SD card talk to the outside world
I have since purchased some from Itead studios I condense the design down
and I came in a little bit more um this interesting stuff
so it's the same maybe are using the same SD
one bit interface to the SD card but this time I decided to have it all
on two layers
I know I'm a one layer fiend but sometimes it just makes sense to have
two layers because now
in this tiny little sandwich stack we have the SD card
in OLED display for my itead studios and
all the circuit board for the motherboard I can
like before plug it in this time I'm only using this for the power so there
is actually no USB interfacing on here
he just gets power so you can plug into the wall now plug it on
like before you can see comes up
and the little block in the bottom right hand means it's working
as I it boots up it's going to be I just booting linux off there - the AVR is just
twiddling its thumbs right now it's
just watching constantly the partition two looking for a change in the data in
partition two
as soon as it sees its gonna act on it.
this has two I2C Ports the first one is dedicating goes the display
the other one however is free to do basically anything that you want with
so now it's booted linux and in a moment it's going to just say
giving an IP address even though it has a connect to the network yet
and in that moment more it's going to connect to the
the WiFi network here and it's going to get a DHCP IP
so this is now the a little
SD card motherboard all in one tiny little form factor
I hope you like this the designs are probably going to be put out some point
they're in the description. Thanks for watching
