Arduino Nano is not recharged by power supply

[mtld01]

Hi,
I am having a problem powering my Arduino Nano rp2040 Connect with a 5V2A power supply.
My project consists of an Arduino Nano rp2040 Connect, to which are connected respectively: an LCD screen (ILI 9341), a thermal printer (Mini Thermal Printer Adafruit), and two buttons.
The thermal printer and the Arduino are both powered by the power supply. To enable the connection between the Arduino Nano RP2040 and the thermal printer, we used a level shifter that converts the 5V coming from the printer to 3V directed to the Arduino.
We believe we have made the correct connections, but the printer is the only component to be powered by the cable.

I do not have the circuit. I am new to this, I don't know how to draw it.
here are some pictures of the components and connections.

Pencil and paper is good enough

Pictures mostly show "spagetti", a collection of criss crossing different cables. It would take a criminal detective to find out, and make a drawing.

Look around at other topics here and see what schematics can look like.
The word "connect" should be banned as it lacks all specific information.

Can't see very well, but if you're powering the nano with 3 volts into the Vin pin it won't work. The Vin pin needs 5-21 volts.
