PCTV microStick (79e) teardown
|PCTV microStick (79e)|
Device is build upon very common IT9135 reference design. I will keep that blog post short as I have teardowned multiple devices earlier having same IT9135 chip, just check those in order to find out some more detailed information.
That same stick is also sold as Hauppauge WinTV MiniStick and its USB ID is 2040:f900. Hauppauge branded version arrived much more earlier - its USB ID was added to Linux driver during kernel 3.14 development time. Actually, PCTV 79e device I got has mistakenly programmed Hauppauge USB ID, but the ones sold now should have PCTV ID.
