Using this HDMI plug to terminal block breakout is easy. First, gather your stranded or solid core wire. Connect the wire to the terminal blocks on the breakout. Then, attach the HDMI plug to the appropriate device. This can help you create a custom HDMI cable or interface. When using, make sure the connections are tight to avoid signal loss. If you're splicing off the I2C or power pins, be careful not to damage the wires. For maintenance, keep it in a dry place and avoid exposing it to extreme temperatures. Wipe it gently with a dry cloth if it gets dirty.
