Quality far exceeded what I expected. Very robust plastic, brass threaded inserts. Combined with the appropriate sized breadboard, and one of those breadboard power supplies, it makes for a very convenient, intuitive setup for a beginner. My 8yo daughter and I are learning together, so we need intuitive :)
Some notes and tips:
- it comes with screws and rubber feet.
- the screws for the pi are 2.5mm, for the arduino are 3mm.
- pro-tip: instead of screws, use tall standoffs ... that way, you have some protection if the board is set down upside down, or something is set atop it. I'm thinking of cutting a small piece of lexan to cover the board, with cutouts for the pins ...
All in all, I couldn't be happier ... just wish they had a version for the nano and due :)
