I'm going to to that again now. Ill also upload the code to the Nextion using the SD and see if that makes a difference.
The teensy should still comm with the radio with no display attached.
It didnt, I also ordered 2 more teensy boards.
The same cable works fine if plugged until a computer and the sds?

Can you test for 5v on that red USB wire?
It doesnt appear to reach 5 volts coming out of the battery pack to power the display but the display is working.
Where should it be.. I have the 4 wires coming from the nextion are all connected
I see 5v and ground from the battery to the Nextion and then the two data lines from the Nextion to the Teensy. I don't see a common ground tying them all together. Without that you will see no potential difference of your data lines to and from the display. You need to tie the Nextion ground to the Teensy ground. All components need a common ground. The radio gets its ground through the USB cable.

Not following. You don't see 5v between the red and black at the display little micro usb board from the battery?
Good catch, in my craziness yesterday, trying to verify power I must have missed that when I moved from the powered usb from the laptop to the battery. I just rewired it, let me test and see what happens now.
That didn't help, still no change.Pressing the button on the teensy loads the driver as I hear Windows load then remove the driver. Only thing is the light on teensy never comes on and hasn't since it was originally programmed. I've also retested voltage on the red wire it is 4.57 volts.

Read the README and docs/install pages. This should have everything you need to build and configure one. Let me know if you have questions.
So the 5th hole on the teensie, as shown below is the ground between the teensie and the nextion?

It can be. Ground is ground. You can just pick one. There should be a card that came with it that shows the pinouts. The last two of the USB port are both grounds and also there is one on one of the corner pins and one in the middle along one side. But yes, that looks like it should work.
Have you tried any test sketches to see if the board works? Something as simple as Serial.println("test"); in the loop?

ok thanks. Still same issue using a new teensie. The teensie button loads and unloads the driver, I hear the windows sounds. SDS does absolutely nothing. I tried just plugging the SDS into the laptop and proscan it instantly prompts for the serial connection so that eliminates the jack the SDS from the problem.
