Using this DIY right - angle Micro HDMI plug is easy. First, select an HDMI ribbon cable from our range. Then, use the flex cable clips to attach the plug to one end of the ribbon cable. You can also switch it with other adapters as per your need. When using with a Raspberry Pi or other devices, ensure a proper connection. As for the note of caution, these DIY cables aren't as durable as ready - made ones, so handle them gently. To maintain the plug, keep it clean and free from dust. Avoid bending it too forcefully as it might damage the internal structure.
