“Just what's needed when working with a Pi Pico and an expansion pack -- particularly a display pack -- as they normally fit back-to-back which makes it difficult to get to the BOOTSEL button and see the display at the same time (without using a mirror or twisting the space-time continuum). It would be even better if it had RESET button, and better still if it had an ON/OFF switch (to power-cycle and reset the pack).”
“Very clever board. The only issue I see is that the pins get mirrored, so that we can plug boards like Pico Display pack 2.0 directly but there are no labels on the board to make us notice this. Therefore, when using it with your own boards, it is easy to connect to the wrong pin. The labels it has, should have been on the two other connectors, not the middle one that Pico connects.”
