This'll be a fun project.
Have quite a few breadboarding and solderable breadboard projects coming up.
This one the only thing to deal with is wiring the programming connector. That's good.
SIPP has power regulation on it.
Does give you choice of bringing power to VNN or VDD pin of sipp that's very cool.
If you conect to VNN you can tap VDD to power experiment. Probably bring in power and leave sipp alone for experiments.
One thing at a time though.
Elvis was right. Peanut butter and banana's is good!
