09/13/2015

10:07 PM Revision 408 (repo2): Fixed audio connector footprint/location. Fixed oscilator footprint (fitted but was too large). Added 16 pin support for serial init rom. Moved reset switch location to allow this. Added pull ups and decoupling to ADC (still untested). Added some more 2.5mm drill holes on the right for stencil positioning. Increased 2.5mm drill size by 1 notch (was too small to fit). Added solder pads for din connectors. Fixed footprint for phono connector. Increased resistor array size to allow fixing by hand more easily. Added pin headers to allow bypassing resistor arrays in case of issues soldering thsm! Added pin header borders to board to make it clear how much space is needed around them for sockets. Made room for jtag pin header socket. Increased version to v1.1. Added decoupling cap to oscillator. Added voltage test point header. Power ADC by 5V (it allows 2.7V to 5.5v but higher reduces changes of breaking it by high voltage inputs I think). Think thats it. Will review a bit then make the next board revision.
