I am well into a project with a feather huzzah and it is powered by the battery as shown in the picture.
So, what is the yellow wire from the battery good for ? It reads about 3.5 volts which just happens to be a supply that I can use. Can I go ahead, wire it up, and use it ?
My other options are to use the DC-DC voltage regulator which is what I was planning to do. I have 1 for 3.5 volts and 1 for 6.0.
My 2nd question is about the use of the velcro to attach the voltage regulators to the chassis. Is it ok to use it like I did ?
