HDMI Cable Tester Board
Easily test custom-made HDMI cables with this HDMI Cable Tester Board from PMD Way. Simply fit 3 x AA cells and you're ready to test.
Plug your HDMI cable into the tester, then use the probe lead to touch each wire on the other end of your cable.
If there's continuity, the matching HDMI plug pin's LED will light and the buzzer will sound.
The HDMI pinouts are conveniently labelled on the PCB for your convenience.
