In “tinyK20 Open Source ARM Debug/Universal Board – First Prototypes” I talked about using a USB thumb drive enclosure for the board, so here is the idea:
The picture actually shows on the top a different board (a Kinetis KL15Z used as wireless data logger with a Nordic Semiconductor nRF24L01+ transceiver. But the idea is the same: to have the ‘thumb drive’ version of the tinyK20 board in such an enclosure.
Not sure how much there will be a need for it, but for sure this protects the board. The other alternative would be to use transparent heat shrink-tubing around the board. At least if the board is only used as a programming adapter board.
And yes, if you would like to have a view on the (current) schematics: I have posted a folder on GitHub: https://github.com/ErichStyger/mcuoneclipse/tree/master/tinyK20
Happy Enclosing 🙂
I designed something similar. But it fits a Bud Grabber Style P case/ Nice thing about these cases is, the PCB is pinched between the two halves. So you don’t have phat screw holes consuming PCB area. Not so nice thing is you have to make the cutouts for the USB connector yourself. And the headroom when the board is in the case is not very much (7-8mm).
But yeah having a case makes the unit a lot more robust and usable. If only because you don’t have to worry about it shorting out something.

Where did the plastic case come from? 🙂
