I would really like to see a bare-bones TinyScreen+ board with just the processor; the same layout as the current TinyDuino but with the Atmel SAMD21 (or maybe a Cortex M3 or M4?). This would give us a board for more CPU/RAM intensive projects as well as 256KB of Flash memory.
So really this product *almost* exists - it could simply be the current TinyScreen+ without the 96x64 pixel OLED and the four input buttons.
