TOFE Adapter and Riser Boards

This repository contains designs for passive adapter and riser boards for used with the TOFE interface.

These adapter boards are transparent to the TOFE bus and have identical schematics, only the PCB design differs.

Any passive PCI-Express adapter or riser which meets the PCI-Express specification should be also compatible with the TOFE interface (but the reverse is not necessarily true).

For more information on the TOFE interface, see the HDMI2USB website. See the KiCad website for more information on using it.

More information about each board can be found in each directory.

Left Angle Adapter

Left angle adapter to allow TOFE boards to be mounted horizontally above the Opsis board.

These adapters where shipped as a bonus to crowd funding backers who purchased an Opsis board and a TOFE expansion board. render of left-angle adapter


Adapter which uses a "straddle edge connector" to raise a board vertically.

Male to Male

Adapter which has TOFE pins on both sides allowing two boards with TOFE sockets be connected together.
