Adafruit 40-pin FPC to Right Angle 2x20 IDC Male Plug Header Adapter

Here is an easy solution for extending your Raspberry Pi's GPIO capabilities. This is a 40-pin FPC to Right Angle 2x20 IDC Male Plug Header Adapter. Use this adapter, which will act as an extender for all 40 pins.

Simply plug the socket side into the Raspberry Pi. Then, keeping an eye on where Pin 1 is, insert your FPC ribbon cable into the 40-pin flex connector. You can use any 40-pin wide, 0.5mm pitch, 0.3mm thick connector, FPC with 'A-B' connections.

If you want to extend the FPC, a 40-pin extender can be snapped on. Finally, you can use a matching adapter board to tack on your HAT or bonnet of choice on the other end.

Note that some HATs, like the Sense HAT or Bonnets with a slim connector on the bottom, will benefit from adding a socket 'riser' or 'lifter' to provide a better grip onto the cable. Examine the HAT or accessory you're extending to ensure compatibility and optimal performance.
