3TrinsRGB-1c output expander

Description:
This expander gives you two extra video outputs (1x composite and 1x s-video) and the RGB VCO outputs in LZX format. You need to sync the 3TrinsRGB to your LZX video synth to use these RGB outputs.
The pcb is powered by the 3trinsRGB via the 8pin connector that connects to the sub-board, the frontpanel has openings (both left and right side) to allow the flatcable to exit your eurorack case.
The sub-board can be manually wired to the 3TrinsRGB or connected via the rightangled pinheader.

This expander requires some soldering on the 3TrinsRGB pcb, so it is not a plug and play project!

note: if you have the newest 3trinsRGB, the Chroma and Luma pads are missing and there are dedicated LZX pads on the pcb, so it is more difficult to use this module with that version.


Features:
1x S-Video (miniDIN 4 pin) output
1x Composite (RCA) output
3x VCO channel outputs (Red, Green and Blue VCO channels of the 3TrinsRGB)
1x 8 pin header (2×4 pin IDC) to sub-board that connects to the 3TrinsRGB via flatcable
This module is powered by the 3TrinsRGB
(but could be powered externally, pads are available on the pcb)

Sync notification:
The LZX Cadet Sync Generator & Vidiot have some issues syncing to the 3trinsRGB.
This happens with & without connecting the 3T-OUTPUT X.
I have tested a several routings.
There might be some adjustment needed of the scroll /pot & button to lock it in the correct place.

These are your options:
-3TrinsRGB output -> Cadet C1 sync input (or Vidiot input)
-external video source (such as a camera or video player) ->LZX C1 (or Vidiot)input, output to 3TrinsRGB video input (this allows for a combination of camera input & RGB VCOs, tested by sean and me)
-external video source (such as a camera or video player) -> 3TrinsRGB input, output -> Cadet C1 input
(this allows for a combination of camera input & RGB VCOs)
-Vidiot out —> VSig Dual Distribution → to both Cadet, MemPal and 3TrinsRGB. (tested by VanTa)

What does NOT work:
-LZX C1 (or Vidiot) output -> 3TrinsRGB input (tested by VanTa, sean and me)
