I have the teensy 4.0 as a flight controller on a quadcopter. i have a radio receiver, MPU-6050, and four motors that are being PWM controller and I plan to add a temperature sensor. bluetooth module and 4 ultrasonic sensors later. I wanna know if I can connect 3 regular LEDs using the digital pins of the teensy and a current limiting resistors in series.
All these electronics are being powered by a 5V 3A power source from the drone, and so then the LEDs' 40mA current is trivial. but everything shares a common power source, so is it possible to control 3 LEDs while the teensy is receiving 5V 3A but also working with other electronics?
I believe I heard the total current on a pin is 40mA, so does that mean I can 1.2A of powering from the teensy? (40mA x 30 pins). I think the max I heard was 200 or so mA
