Soekris DAM1021 s/pdif Inputs Board

I made a little s/pdif input board for my Soekris:

2015-12-05 16.41.34 (Large)

It has a coax input, two Toslink, and it includes a USB-to-serial adapter so as to facilitate easy update of the DAM’s firmware.

It also has an on-board low noise LDO for the Toslink modules and their switch, plus one more LDO for supplying the 1.2V necessary for the coax port.
