There isn't much out there that protects the Pico while still allowing you full use of the GPIO so we had to design our own...We also like to be able to pin directly to the breadboard and this seemed to be the best solution to keep all wires in place for prototyping.The slider was subject to debate but we settled on including it as a visual clue for folks juggling projects with multiple devices.Certainly there are improvements to be made here but it works as is and we are going to update this as we use it and learn.If you decide to buy one, rest assured the money will be put to good use developing 3D printable rockets.Thank you,
