Published on 2022-08-26 in µGame 22.

The second version of the PCB and case just left the @Elecrow fab and should arrive here early next week.

I made the following improvements:

Added a qwiic connector, so you can extend it with sensors. I decided against having a 12-pin connector like in all the other PewPews, because this is mostly supposed to be for the games, but I still wanted an easy way to connect things.
Proper footprint for the kind of crystal oscillator that I have.
Swapped places of the USB and speaker, I think it’s better when the USB plug is further from the edge.
Fixed the short on the speaker.
Moved the reset and boot jumpers to the back of the device, so that you have access to them with the case on.
Added vias on the SWD and SWC pins, so you can access them for debugging.
Added a cutout for the switch, and moved the switch deeper, so it no longer sticks out of the device’s outline.
Used smaller holes on the front plate, so it should work with the nice black screws I have.
Rounded the edges on the case elements.
Added a coutout for the qwiic connector.
Moved the labels for the buttons to make them more visible.

Overall, it’s all small changes, but they make the device a little bit more convenient and nice. I considered switching to USB-C connector, but I couldn’t be bothered preparing the footprint for it.
