Will I2C-Tiny-USB work with LilyPads based on the ATTiny85 #18

I want to try to replicate this project. However, I have a hard time obtaining a ATTiny85 chip with a MicroUSB-Port (like the blue one here: https://www.aliexpress.com/item/32432747996.html). I tried to order it twice but the order got cancelled each time as it doesn't seem to be available atm.

However, there are plenty of offers for a LilyPad with the ATTiny85 (e.g. here: https://www.aliexpress.com/item/4000943968380.html).

Is there any reason the project would not work with this board?

Side note: I also found offers for the digispark, however I would prefer a solution with a MicroUSB cable.

I tried it out myself, the project also works with the LilyPad based on the ATTiny85.

For future readers: if you have problems flashing the firmware on you ATTiny85, make sure it has a bootloader installed. I had a very hard time to realize there was no bootloader on my LilyPad and then to flash the bootloader on the chip. But it did work.

@harbaum: in case you want to add the board to this page I can provide some pictures.
