Also needs an LCD and LED for test status. BTW, the original beagle-tester required a network router and a computer for some of the tests for testing BeagleBone Black. An external HDMI monitor was also needed. Perhaps something like Amazon.com: Audio Express AXHDCAP 4K HDMI Video Capture Card, Cam Link Card Game Audio Capture Adapter HDMI to USB 2.0 Record Capture Device for Streaming, Live Broadcasting, Video Conference, Teaching, Gaming : Electronics can allow it to be more self-contained.

To detect and verify the CSIPR HDMI output, are we planning to use a computer vision-based approach to analyze the output, scan barcodes, and automate the testing process? Or will this step remain a manual verification process?

Also, Some Ideas from balena AutoKit, like Containerization, Remote Device management can be added here.
