Hello MartinMartin8bity escribió:The board in this topic looks slightly different than the one in the SVN? The one in the SVN looks like it has audio connector and missing EMI filter. I would like to make this tiny board for me and my friends in Czech who are building the ZX Uno too. Where can I find the latest data, please?
The EMI filter is not needed. The latest version is the one in the SVN. Initially I've employed unused pins from VGA connector to transmit the audio. The problem was that these pins are not really unused in certain monitors. To avoid the problem, I have patched the first version of the board like this:
Sorry, the black is not the best color for the PCB. There are 2 cuts for the audio tracks and one complex cut in pin 9 of VGA connector (four sides).
And I have done a second version with a separate connector for the audio. This way you must use 2 cables (VGA and jack) from ZX-Uno to Scart, but it's a safe way.
