Hi David,
following your recommendation, I will hook my motor controller
and my tiny 2.11 in parallel. I get two 11,6 V output from my battery,
one for the ESC, and the other for the tiny.
Now I intend to connect the tiny directly to one of the output
provided by the battery, in order to check if the power supply module
(PTH08080WAH) and the 5 / 3,3 V regulator (LM3940) are working
correctly. Since you have already worked with this setup, your
comments will be very helpfull for me.
Thanks. Santi.
