Once I figured out how to set up the unit after finding the documentation sent to me when I purchased the programmer, everything went perfectly. At this stage have only tried on ATmega48 & 88 & 328P. Microprogrammers, excellent product, thank you. Shipping was lengthy due to COVID-19 crisis.

You should check your Tindie messages. The instructions were sent to you the very same day you ordered the unit. If you need help all you have to do is ask, there is no need to leave a negative review.
