“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.”
“The SIL (Serial in-line), connectors are a very tight fit. Once an item is attached it's very difficult to remove. ZIF sockets would help but would increase the cost and size. A parallel lift lever would be a useful accessory. Additionally, mounting holes to enable fitting in a box would be useful.”
