Description:

Audio board upgrade for Official RGBtoHDMI CPLD board with cable terminating in a 3.5mm stereo jack socket.

The audio board is soldered, piggy-back style, to the top of the CPLD board by soldering to the GPIO socket pins. The audio cable will need threading through the top right mounting hole on the CPLD board and then soldering to the audio board.

We recommend drilling out the top right CPLD mounting hole, as in the photos, to 3.2mm, this will enable the cable to exit the case easily and provide some strain relief, a blob of hot glue should help hold it in position to get the best results.

NB. Only known to be compatible with the RGBtoHDMI board by Ian Bradbury. May not be compatible with RGB2HDMI or other similar boards.

RGBtoHDMI CPLD board Pi Zero, microSD Card and case not included.
