I want to drive 15 servos (+ some sensors) on the Teensy 4.1 but i'm afraid im exceeding the max current draw.
The servos are powered by a separate supply, so my question only applies to the signal pins for the servos.
I know the max current draw per pin is 25mA, but if there is 15 servos that would make 375mA + 100mA for the microcontroller chip itself and not counting any other attached sensors.
The last time i attached all servos (12 of them) the teensy stopped working and had a short circuit between 3.3V and GND. so i wonder if i need to limit the current of the signal pins with a resistor.
Any help is appreciated!!
