MiSTer add-on boards were designed around the DE10-Nano form factor, which doesn't have a full-sized USB type A port. As such, a small connector is needed to interface the official USB hub.
The USB bracket is compatible with:
- Caseless setup
- PCB case
- Aluminum case
- 3D printed cases
- other, third party cases
I had been using a more conventional USB bridge. You know the one, a little pcb strip with a micro USB on either end. It certainly got the job done, but it looked a little janky. This is a nice little upgrade for the price.
