Title: How does my trackpoint module connect to controller
Post by: ownfed on Fri, 27 November 2020, 02:39:07

I have a new trackpoint module, it just has 6 pinouts which is :
NC SDA SCL INT GND VDD (which has no mouse button pinouts probablly)
I have seen almost every trackpoint module from thinkpad, which is different from mine
could anyone here please help me about the connection between my trackpoint module's pinouts with a controller?

It's an i2c bus trackpoint module. You would need to use a microcontroller to convert that to USB. I believe there are trackpoint modules which are USB or PS/2, which could be easier. You won't hook this one up without a dedicated converter (might exist, don't know), or without programming a microcontroller yourself.
