Bill of Materials (Atom Board)
This is a bill of materials for the Atom Video to HDMI Adapter with predominantly digikey part numbers (thanks to John Kortink for these)
Latest schematics are here:
Note the 6 bit board combined with the analog board will also work with the Atom but DIY construction of this board might be easier at it is mostly through-hole.
All resistors are standard metal film (0.3W or 0.6W) 1%
