Making a Teensy teensier

Post by Renate »

I like the Teensy 2.0. It has enough capability for many USB applications.
It's pretty small, but the mini USB connector and a mated cord makes it a lot bigger.
I've used mini USB plugs without the shell.
Still, to get the total length under 1.5" you have to do some radical surgery.

First you use a Dremel tool with a cutoff wheel to chop the mini USB socket into pieces.
Then use solder wick and remove all the pieces.
Using a bit of perfboard as a template, drill two extra holes in the PCB using a #64 drill.
Cut away a bit of the ground plane on the underside of the PCB where the new pins will be.
Insert a 2 pin strip into the board.
Solder wires from the mini USB PCB lands to the new 2 pin connector.

Yes, you can easily destroy a Teensy doing this.
Only attempt if you are confident.

On the newer 3.0 version, the USB signals are also available at test points on the bottom side. Details here:
