Using the Pimoroni Flat HAT Hacker
« on: December 07, 2022, 09:08:28 PM »
I've been thinking of ways to reduce the thickness of the stack of boards that comprise a pi-stomp. The goal being to use a thinner extruded aluminum enclosure (for example: https://www.hammfg.com/files/parts/pdf/1455P2201BK.pdf) Here's the hacky part. I want to use a Flat HAT Hacker (https://shop.pimoroni.com/products/flat-hat-hacker)with a 90 degree header on the Pi (removing the original straight header). In this scenario the Pi would connect on the right side of the thinner board sandwich. This would eliminate an entire layer of the board sandwich and reduce the total thickness by a third-ish? Will this work?

That's an interesting idea.

Good luck unsoldering a 40-pin header  :-\  better you than me.
I'd probably look into something more like this for flipping the pin direction 90 degrees:

Additional things to consider:
- 26mm for that enclosure is not much height if you have any stacking at all (eg. flat-hacker/audio card)
- The pi-stomp Core board depth itself is around 28mm because the encoder/pot/LCD are on top and the very tall jacks are on the bottom.  You might need to off-board something.
- Hat hacker type devices don't always result in the pin direction you want.  You cant just flip pin 1 to be where pin 40 should be.
