Tobi
Tobi is an expansion board that provides **DVI display, 10/100baseT Ethernet, USB Host, USB OTG, USB console, and Stereo Audio to any Overo® COM.
This version of the Tobi Board is deprecated because it mates only with Overo COMs using the discontinued AVX connectors, manufactured before 2020.
Overo COMs manufactured since January 2020 use Panasonic connectors. The correct version is available here.
Tobi 
Provides DVI-D signals on an HDMI connector plus 10/100baseT Ethernet. Also features USB Host, USB OTG, USB client, Audio Stereo-out and line-in, and a 40-pin header with GPIO, PWM and A/D lines - an expansion board for any Overo COM.
This is our most popular Overo COM expansion board. Engineers and makers are using it as a basis of their custom expansion board for the Overo COM.
Once you have tested the board, you may use Geppetto online to design and customize a board for your own project.
