Hi,

I have two of these LED displays that I want to connect to a Teensy 3.6 and power. They require 5v

Right now I am just powering them with 3.3 and they are not very bright.

I think I read somewhere that there is a pin on the Teensy 3.6 that provides 5v. Is this true? Which pin is it exactly?

thanks, Nick
 
When powered by USB cable there will be 5V on the (internal) VUSB pin labelled on the rear of the card and if the VIN <> VUSB trace has not been cut - that same 5V will appear on Vin pin. The current on that pin is limited by the Host device on the other end of the cable - typically at 500 mA.
 
@defragster Ok got it. thanks. I will try and grab it from the Vin pin and see how that goes.
