I've been using the Tessel since version 1 and now I've switched to Tessel2
I'm running into an odd behaviour and I'd like to ask for some help, I've got a spare drone engine that works on 3.3V, if I plug the engine in the 3.3V and GND port it turns on successfully, however if I do something like
and I plug the positive into the port A5 the the engine does not turn on, I switched the engine with an LED and it turns on but is not as bright as when I plug in the 3.3V, to overcome this problem for now I'm turning the port on and off when I need it to
but it's not a long term solution, same goes for the pin B7, I'm trying to use
analogWrite, but I get the same result when the analog value is 1. I tried with a voltmeter and the output is around 2.8V rather than 3.29V
Any idea on what's happening? is there a way to fix it?
