Integrated, compact micro+display
For ATMega328p with onboard 1.54" high res TFT display
I am a big fan of integrated micro/displays. The Olabec design is marvellous. It has an onboard USB/FTDI along with many i/o pins broken out. The display controller is a ST7789, so there are many libraries and examples that work on the board. Finally the board has an acrylic case so it is ready to use.
