@gerbenvs Hi. For me in the module’s config the qrSize works fine so check if you have place it correctly in your config file or else like sdetweil mentioned try to abjust the image size through your custom.css

@sdetweil I am confuse a little bit. From what I read I think usb port is better since it powers itself from the pi’s supply and not from the board. Although I have only one availiable on my pi because all others are used for mouse, keyboard and mic I think I will give a try and see how it goes. Thank you very much for your reply.

Hello everyone. I hope I did’t open this topic in the wrong place.If so pls correct me. I would like to ask if Rassberry pi 3b+ can power an arduino uno R3. On the pi I have istalled magic mirror and GA and I use some gpios of the pi for the pi’s fan and an RGB led strip for GA status. The arduino is used only for lighting another led strip with various effects. Both led strips is connected to external power supplies so no further power consuption on both boards. Also if it is possible which way is better? Through the Vin, the 5V pin or usb port? I am asking this only to avoid using one more power supply since there are already 3. One for the pi, and two for the led strips. Thank you in advance.

@Egnos I didn’t know you want a picture too. Although this, this and this seem to have a picture of the article but better is to check them yourself to see if they fit your needs.

@Egnos Why don’t you try different modules?

@kayakbabe My problem was not the power because I power the led strip from external power supply. I figured out that somehow the GPIOs I wanted was not set as output mode and high state. I set them and everything is working fine. Thank you for your reply.

@BKeyport said in GPIO'S:

Smart LEDs are highly reliant on data timing being exact.

The problem is that except GPIO22 which working all other GPIOs I checked never worked. Even if the command show it works. Well if I do not get a valid answer from rasberry forum to fix it I won’t use the status leds. I can leave with that :smiling_face_with_sunglasses:

@BKeyport Thank you for your reply. what do you mean bu saying that the problem is timing? I already have made a topic in rasberry forum and waiting for reply.

Hello builders. I have a problem with my rasberry. I want to connect a led strip to use it with GA status. I follow this guide to connect and control it but it seems that most of gpios do not work. Only one color lighted in the strip so I took a voltometer and connect the black wire to one of the rasberry’s grounds and the with the red one I start touching the gpios and only one of them had near 3.3v. All others was below 0.8v. Even when I run the script for the status I get the output tha GA is in listen status and so the GPIO17 should be in high state it has no power. Does anybody have an idea of what is going on? Are the GIPIOs dead? Thank you in advance.

@sdetweil No problem. I will visit the store again when he has the glass to see it myself and if it is possible to see it working. After I will make up my mind.
