This is the final revision before I order a prototype, unless someone notices something wrong with the board. It's basically a completely new hat. I also had to make a few minor changes to the minigun itself. I'm still not completely happy with the stand off hole situation, and my trace routing is making me more and more nervous. Especially on the Minigun itself, everything is super compact. Frank did a very good job fitting everything in, it earns the Mini part of it's name.
Changes to Minigun
- I was worried about it only sitting on 1 standoff and 2 headers so I added a second stand off hole. It was hard to find a good spot on the minigun board for the hole though so it's still a bit awkward
- Added sound to the Video header to make it an AV header. Uses the sound off of the 3.5mm jack so it should turn off when headphones are attached
- Switched a 1x4 pin header to a 2x3 pin header and moved the header close to the 3.5 mm jack.
- Removed the power header and instead used the power header between the controller ports
- rerouted the RGBS traces a little bit to allow the signal to be forked to the AV header
Changes to the AV Hat
- Added Left and Right Audio RCA connectors for sound output.
- Moved all the RCA connectors to the front, they will be over the controller port. S-Video is still to the side
- Added a top level and bottom level GND plane for the AV connectors.
- Redid the component layout and all of the traces.
