Topic: Blackberry trackpad connector - 20 small pins. Plug or ribbon? (Read 1 time) previous topic - next topic

I want to make a really tiny wireless mouse, and I need to connect a Blackberry optical trackpad to an Arduino, and I'm not sure how to physically connect to the right leads.

How do you guys solder to really small stuff?

I have two options:

This connector type thing, about 1cm in length (.39"), that I don't have a female plug for. It appears it doesn't exist.  :smiley-sad:




Or this ribbon that I have no idea how I could solder something on there. These pads seem a tad bigger than those pins.



Also, I suck @ soldering  :smiley-eek-blue:
I'm beginning to see why I couldn't find anybody successfully interfacing one of these.



Thanks.

"duende_azul" post put me on the right path...the pinout I found on another forum.

This datasheet was key for me...registers.

@andystedman do you have any success in interfacing and running the trackpad? If yes, can you help me as I am very confused. Any schematics or code will help. It would be very nice of you. Thanks
