3.3 Voltage

[troy2018]

I am new to Teensy and I am now using Teensy 3.2. I am building something for a school project that involves motors. I have a (maybe stupid) question about the voltage of the pins. When I connect a motor directly to the 3.3V pin I get a lot of rotation power, but when I connect it to a analog / digital pin I get little power. How can I get the maximum rotationpower out of my board?

Thank you

Designing circuits (independent of the used MCU, be it Teensy, Arduino, ESP) requires studying data sheets and at least basic knowledge in electronics. From the Teensy data sheet, you can see that a pin can source a maximum of 10mA which is not enough for a motor. So, an external driver must be used to drive the latter. Connecting a motor or any other low impedance consumer like a speaker directly to a MCU pin risks to damage the chip!
You might have a look at Sparkfun or Adafruit. One of them might be offering breadboard-compatible motor driver modules and corresponding software libraries.
