GCDual YPbPr Multiout QSB

2 layer board of 0.76 x 0.64 inches (19.2 x 16.2 mm).
Shared on March 6th, 2018 13:38

This is setup to use HDRetrovisions SNES Multiout connectors. Some small filing might be required to fit. There are 3 small ground pads below some of the pins, this is for the MODE input on the GCDual. if you did NOT setup MODE input on the GCDual then make sure they do not make contact.

Strain reliefs I used: https://www.amazon.com/gp/product/B019DCXAE8/

220 uf Tant Caps: F930J227KBA

Here is an installed image (NOTE: The PCB is installed upside down in this picture. I had to desolder the PCB and flip it.)
