NES-101 back panel for TRRS composite mod

thingiverse

I made this design because it's possible to replace the RF module with a larger TRRS contact that fits in the RF hole of the original backplate using a common technique. Unfortunately, I couldn't find a suitable TRRS contact easily available here, so I designed a new backplate that can accommodate a 7mm TRRS contact instead. This is much easier to purchase. I ordered my contacts from Mouser (490-SJ1-43502PM). This approach results in a cleaner installation compared to drilling holes in the case for RCA contacts. To implement this design, you'll need to remove the RF module and also install a new DC contact since the original one is melted into the original backplate. Next, connect the 7mm TRRS contact to a 3.5mm to 3xRCA cable for both video and audio signals.
