Default Any Interest in a 2:1 I2S switch board?

I am laying out a simple 2:1 I2S switch board for my DAC project to switch between my 4:1MUX board and a USB Receiver interface. I am also including a 2:1 switch for switching master clock sources. The board will switch via 5V logic level. and the two switches can be operated independently.

I'm curious if anyone else would have interest in one? I only need one maybe two boards and will have extras to meet the min order.

I am trying to decide what sort of connections the board should have? right now it is set up for solder pads but I could easily design it for phoenix connectors or RJ-45 jacks etc. or possibly both depending on interest level.

I dont know what the cost will be just yet. but I would estimate maybe??? $20-30 plus shipping.

Please email or PM me if you would have interest.

I figured there would be more interest in this with all the talk about USB to I2S and DIY DAC kits etc.

I was thinking about cobbling something like that together, but it's low on my priority list for now. Vishay has some quad switches which should work, and they are through hole.

Oh I guess I should have been more specific. This board uses a Quad 2 channel Multiplexer IC and a Single 2 Channel Multiplexer IC. A much more elegant solution than Switches or relays like was mentioned in the Twisted Pear forum.

This is a proven design that is available in a commercial product already that has been adapted as a stand alone board. It runs off 5v and switches via 5v logic level. it can be controlled by a micro-controller or you could use a simple SPDT switch.

What's the advantage, all you're doing is switching. There are no speed requirements involved. The Vishays use 5V logic level. Don't make it more complicated than it needs to be, unless you're just having fun with the control circuitry. Am I missing something here?

Best, Bill
