NES Hub (Expansion Port)

Here I wanted to share the details about my newest project/product, called the NES Hub.

The key is a custom made connector for the NES Expansion Port (see 2nd picture), so no more cutting/sanding of connectors needed!

The NES Hub brings Bluetooth functionality to the NES, powered by the great open source project Blueretro by Darthcloud.
Through that, its possible to connect basically any BT Controller, including the NES Switch controllers. It also supports 4 controllers by emulating a FourScore Adapter.

Expansion Audio can be enabled, either by using EXP2, EXP6 or EXP9, using a DIP-switch.

On top of that, most signals available on the Expansion Port are broken out to 3 Mini Displayport connectors, grouped by controller signals, EXP signals and CPU signals. I wanted to make these signals available for anyone who wants to have a go at developing addons or just wants to tinker with them.
The pinouts of these connectors are attached as an excel file.
My own (basic) addon is an adapter for SNES and famicom controllers using the port with the controller signals.
There are already ideas for an FDS addon (Muramasa) and EPSM addon (Perkka) in the works.

I´m open for suggestions Ideas for other addons and happy to help and test if anybody wants to develop something.

It would be great if the basic informations + pinouts could be added to the wiki, to make them available for anyone interested.

The NES Hub is available for preorder at 8bitmods and Stoneagegamer at the moment and scheduled to release this december.
