SparkFun Pico Add On Flipper for XRP (COM-28236)

Anyone familiar with the Raspberry Pi Pico development boards, has likely seen the various HAT (Hardware Attached on Top) accessory boards. If you are like us, you've likely run into a simple design limitation with the HATs; they can only be connected in a single orientation!

Whether a HAT is attached above or below a Raspberry Pi Pico, they all have a fixed orientation. At SparkFun, we have come up with at simple solution to this problem, the SparkFun Pico Add-On Flipper for XRP. Our Pico Add-On Flipper takes the standard pin out for any Raspberry Pi Pico development board and flips it over, as if you had physically rotated the board over (facing down).

How is this useful? Say you have a project that uses a Raspberry Pi Pico development board and:

  • the board must be in a specific orientation to access its USB connector. However, the wiring or connections to the perfect HAT for your project is on the wrong side. With the Pico Add-On Flipper, you can flip those connections from the right-side of the USB port over to the left-side (or vise-versa).
  • the perfect HAT for your Experiential Robotics Platform (XRP) kit, is not intended to be attached on top of the Pico, but underneath it. For example, a display board where the screen faces downward. With the Pico Add-On Flipper, you can take the (hardware attached on the bottom) display board and flip it over, so that it can be mounted as a HAT (above the Pico with the screen facing upwards).

Additionally, we also provide a Qwiic connector and reset button on the edges of the Pico Add-On Flipper that users can easily access.
