It’s called Digispark-Kickstarter-USB-Attiny85-Pluggable-Development-Board and consists of a board with 8pin socket, a separate attiny85, a micro-usb jack, some electronics and 42 + 31 holes.
Connecting it to a USB port results in a USB device, which is not recognized (Device Descriptor Request Failed) and thus does not allow for a driver to update.
Does anyone know this thing, which I guess has an empty attiny85 and first needs something basic to be uploaded to make it talk USB and eventually behave like a real digispark.
I got an usbasp programmer or could use an Arduino as ISP, but first wanted to get feedback:
- Does anyone know these boards ?
- Is this “virgin” (?) behavior normal ?
- Could this micronucleus bootloader be the way to go ?
- Are the 6 pins required to program an attiny85 directly available on that 4*2 header pins/holes ?
- If yes, does someone know it , or do I have to search by multimeter, which attiny pin shows up where?
Thanks for reading, and even more for hints and help
