Hi everyone, I'm a new Teensy's user. I got Teensy 3.5 for my robot project. My Teensy get burn at L3 component after testing for 5 micro servos motor and a DC brushed motor driven by a motor driver. For 5 servos, I connect the servos with external 5V power supply and connect GND to Teensy with servos signal directly conected to the Teensy. And for DC motor driver, I connect two enable pins and one PWM pin directly to Teensy. After an hour of testing the robot. My Teensy got a windows access deinied error. Then I found that L3 components get burn. So what made my Teensy get burn? This is a costly "learning experience". 199180.jpg
 
Did you perhaps use the AGND pin as the GND for your servo's? That would explain coil L3 to get burned out.
It's better to use the digital GND pins of the Teensy for common ground.
