Raspberry Pi CM4 TV Stick

WS2812 LED strip arrived and after some soldering works nicely

Next will be testing WS2801

Pre-production boards have arrived!

Time to test ambilight connector.

Tested built in IR receiver and to a big surprise it can receive signal despite of being behind TV and looking towards the wall.

Also tested with eMMC version of CM4 for flashing.
To enter eMMC programming mode:

• USB multiplexer selector switch to USB-C position
• Press and hold User Button
• Connect USB-C cable
• Release User Button
• Follow software procedure

Still have to think how and where to fit connector or solder pads for Ambilight...
