I designed another PCB... Small preview without revealing what it will be. It'll arrive mid January, though.
They will be manufactured by @aislerhq again, using the 20% December discount for using their #KiCad plugin.
It'll have the option to use an AVR DA compatible #microcontroller or a #tinyAVR one - I added options for both that I have in stock (AVR32DA32 and ATtiny814). Since it won't use many pins, I could have used smaller variants, too.

I received a few AVR128DA32, which have four times the flash size - now I don't have to keep this in mind while experimenting. Also, I soldered a small #perfboard for the #GameBoyPrinter emulator. I used a few 30AWG flexible silicon wires to route the connections - they fit perfectly through the holes. It's 3cm x 7cm size and I placed the SD slot on the bottom to keep it intact, and the connector for the link cable underneath the display. Now I have to decide which size looks better, 1.3" or 0.9" #oled.

One reason for this dev board was to build a #GameBoyPrinter emulator for my #GameBoyCamera. The ATtiny814 just didn't have enough RAM. The NeoGB-Printer is a bit too specialized, I'll adapt the #Arduino GameBoy printer emulator from https://github.com/mofosyne/arduino-gameboy-printer-emulator to my needs. It'll have output on SD card and maybe a TFT status display, the prototype is already wired up. It'll give it a proper board later (might just be a #perfboard).

I wanted to try out a few new things. So, I designed a development board for the AVR DA #microcontroller, the 32 pin #TQFP looked like something I'd be able to hand solder. I really like #UPDI from the ATtiny814. This is the result, my first four layer boards, first time with logos and an image. The image of #Frieren was a bit too small, though. Manufactured by @aislerhq again.
