Hey micronucleus! I was wondering, because im having a hard time sourcing attiny85's.. if micronucleus works on the attiny202 witch is much more available i think! Or maybe there are similar chips? i want to include an attiny on a board im working on, but without external uart or specialized programmer, thanks for reading! |

In principle it should be possible to port Micronucleus also to newer ATtiny. But this has not been done yet. On ATtiny202 you can also use UPDI, which just requires a single wire and a USB2TTL interface: |

That still requires a sperate usb ttl chip, witch is what im trying to avoid. My current design is very nice in it only requires a single chip. Maybe i can help experiment porting to the 202? where would i start? or is there a better place to source 85's? they're really expensive/sold out everywhere i checked :c |

Did you manage to get V-USB to work on ATtiny202? Btw, the 202 only has 2kb of flash. Micronucleus would eat up most of that. Digikey still seems to have plenty of ATtiny85, btw. |
