Iam just building it. I think i have to get another OTG-Adapter. Connected it to my pc and both red led turn on. As i understand that mean the arduino is working.

Yes that means it's working.

Try re-inserting the LCD's ribbon cable.

Im assuming it was working before the update? Is it a usb audio or PWM audio?

Was it working before? Because I have already stopped making this board for quite some time already.

I made a post, Raspberry Pi Headless Wifi Setup which works with the new raspberry pi image which requires you to setup your country location first before the wifi works.

Or you wired the battery directly to the powerboost’s output?

Do you have any pictures of your wiring and soldering. Wire the pi/screen to the 5V and GND pads. (you said you wired it to the EN pin which does not make sense to me.) Check this diagram https://i.imgur.com/74mlicv.png Just bought a multimeter - says im getting 4v between the screen's board and th...

Do you have a spare battery to test? Make sure it’s fully charged or charged enough. If the issue persist then check the wiring from the battery. Check also the voltage output of the powerboost while the battery is plugged. It should be around 5v.

Is it for a pi zero or pi3 build?

You can also try updating the os with:

You need a mosfet with logic level gate. Something like a IRF510 or IRF520.
