I’ve started a project using a picon zero and a Raspberry Pi B+,
I’m using a 6v battery (actually four 1,5volt batteries in series)
everything was working fine both using servos and some small motors,
however today while I was running the motorTest.py I smelled that something was kind of burning and then stopped everything and removed the batteries, waited a while and booted the pi again,
now the picon zero seems that is not working. the led is fine but it doesn’t turn the motors on,
since everything was working fine and the voltage and currents are in the working range what could have happened?
