    Thank you Paul for having quickly answered but I don’t get it. Do you mean that actually changing the number is probably useless? So what should I do to get 250mA?
  2. Does the Teensy 3.2 gets from the computer the 250mA is it said to provide?

    Hello,

    I have just switched from a Teensy 3.1 to a 3.2 because I suspect the former cannot provide enough current to power 2 Sensel Morphs. The idea is to use the Teensy as a MIDI device...
