My home made emmc adapter - GSM-Forum

Thank you Blang and NoName for all the hard work, adapter schematic and patience

This is for everybody that does not want to buy the adapter for 12 Euro + shipping.... just do it yourself like I did.
Maybe 2 Euro's for parts and 1 hour to arrange and put it together.

Instead of micro USB port for the power I used pogo pins because I will power it with my power supply. ( all my USB ports are filled up on my computer).

Here is the back side

Testing VCCQ

Testing VCC

All contacts from Easy JTAG box to the adapter "out" were tested.

Hope you like it

The Schematic is similar to here :
http://forum.gsmhosting.com/vbb/f672...nnect-1691327/

But I used 2 " Low drop out voltage regulator " instead of one that has both 1.8V and 3.3V

Low Drop out voltage regulator
Just look for :
input up to 15V output 1.8V 1A ( or 0.8A)
input up to 15V output 3.3V 1A ( or 0.8A)

The rest of the components values are in the shematic that Blang posted.
