RM4.00
  • USB TYPE A

    Quality USB Type A Standard Female Sockets. These will work great if you need to repair a USB socket on consumer device or you would like to add USB to an electronics project you're working on.
    The pinout is on the bottom and will fit on perfboard but you will have to

     

    a) drill out the holes for the tabs on the side or

    b) fold them out of the way.
