On USB Type C and the Teensy 4.1

Hi Everyone,

I am working on a project and I was trying to figure out a way to use a USB Type C connector that can pull 1.5A of power and pass the D+ and D- to the USB 2.0 device pins on the Teensy 4.1.

VBUS is connected to the VUSB on the Teensy 4.1. From what i've read this will allow a maximum of 3amps @ 5V if the port supports it. It looks like most modern laptops will provide 1.5A + over USB 3.1 ports, so this should in theory work?

My questions:

1) Does this make sense?

2) Would two pogo pins on the board be sufficient to connect to the D+ and D- pins on the teensy? Has anyone tested this? Assuming I would solder the Teensy to the board

3) Would it be possible to detect if the current supplied was LESS than 1.5A (or 900ma) and disable/dim a bunch of LEDs on the board? Or not allow the device to power on at all?


Thanks,
