To program the the tinyAVR 1-series and tinyAVR 0-series you need to use UPDI (Unified Program and Debug Interface).

If you like what I am doing please consider supporting me on Patreon: patreon.com/dustinwatts

Schematic of the UPDI programmer: http://dustinwatts.nl/updi_programmer/Schematic.pdf

Thanks to Spence Konde and ElTangas it is possible to use an ATMEGA328P as a UPDI programmer. In this video I build the PCB I designed. It is using and FT231X USB to Serial chip and the before mentioned ATMEGA328P.
