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 encountered a simple design limitation: The HATs 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 devised a 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 it over (facing down).
How is this useful? Say you have a project that uses:
A Raspberry Pi Pico development board must be in a specific orientation to access its USB connector. However, the wiring or connections to the perfect HAT for your project are wrong. With the Pico Add-On Flipper, you can flip those connections from the right side of the USB port to the left (or vice 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 with a downward screen. With the Pico Add-On Flipper, you can take the display board (with hardware attached on the bottom) and flip it over to mount it as a HAT (above the Pico with the screen facing upward).
We also provide a Qwiic connector and reset button on the edges of the Pico Add-On Flipper that users can easily access.
