Using this connector is quite easy. First, if you have a BBC micro:bit or a CLUE, just plug it into the connector. For the Sunken Right - Angle style, it will fit nicely and align with the PCB. Make sure to align the pins correctly when plugging in to avoid any damage. When handling the connector, be gentle as it's a delicate electronic part. Don't expose it to extreme temperatures or humidity. To maintain it, keep it clean and dry. If there's any dust, you can use a soft, dry cloth to wipe it. Also, when not in use, store it in a safe place to prevent it from getting bent or broken.
