My issue is the connection port, anyone know where to order this item

Hi,

Search online for (insert model number of tablet) USB connector to get results for suppliers of the part.

I found this supplier by searching for Insignia Flex 10.1 USB connector but the connector may not be the same for your particular model variant.

Even though it is also a micro USB connector, the difference will be in the position of the mounting lugs on the body of the connector as these can vary between connectors and the motherboard lug mounting solder tabs will be positioned for the correct connector. The connecting pins will be the same however.

Here’s the ifixit Insignia Flex 10.1 Motherboard Replacement guide which will help to gain access to the connector etc.
