My new PCB has just been mated with a S3E500 starter kit for the first time.  They look quite good together I reckon?

The boards mated together for the first time. Not a made combination, even if I do say so myself!

The daughter board is a USB interface to the S3e500 using an FTDI FT2232H IC and the other chips are an Spartan 3A50 (acting as a level shifter) to a TI ADS4142.  At the moment it is just a test board to see if I can get a reasonable speed analogue signal into the S3E chip and then across a USB interface. Applications? I don’t know – I just want to do it!
