I just stumbled across the Nanite85 project by Tim. It is a really nice project that has the same goal as mine. It also is a drop-in replacement for the ATTiny85 with a DIP-8 footprint and a matching pinout. However, since Tim started with a 'who has the smallest' table I want to add my board to it:
|Olimexino-85s||12.7 mm||16.9 mm||214.6 mm²|
|Nanite||10.1 mm||17.8 mm||179.9 mm²|
|DIL-Duino [with USB]||10.2 mm||14.2 mm||144,84 mm²|
|DIL-Duino [without USB]||7.6 mm||9.8 mm||74,48 mm²|
Wohoo, did it! Both variants are smaller.
But to be fair, the variant with USB is almost the size of the Nanite.
What do we learn from this? It is almost impossible to have an idea no one ever had before :)
