Hello, I am new to Raspberry Pi and I have the raphael kit. I am stuck on the cmd prompt where it says to place the RFID reader, it does not find either of the cards, and I am hoping someone out here can offer some advice on what I might be doing wrong.
We recommend that you provide us with a screenshot of the problem, so that we can help you analyze the problem.
Please follow our tutorial in order:
https://docs.sunfounder.com/projects/raphael-kit/en/latest/python/2.2.10_mfrc522_rfid_module_python.html
So I get to step 4 and the reader does nothing, also, the chip blinks red, it does not stay solid. I do not know if it should be solid.
After you run the code, point your white card or electronic key at the MFRC522 RFID module to recognize it. Only then can you read and write.
Okay, so for clarification, I have used both cards provided with the kit and nothing happens. The cmd line just stays the same as the pic I uploaded. I am using a Raspberry Pi5, I read there is some GPIO trouble between the 4 and 5 with this kit, is that maybe a cause?
We are very sorry, we have reproduced the problem you are experiencing and it will take us time to fix the problem.
For now you try to play with C and see if it works properly reading and writing yet. We have tested it with no problems.

Thank you for your help, I will do that

Hey ! I’ve also got some problems with the scans… however it does work sometimes, but it is very hit or miss. Sometimes it takes 15-30 attempts (bringing the card/tag slowly to the reader from various angles). I was wondering, did you all look into the code and find anything to adjust? Or is this potentially a hardware issue? I’ve had this problem with both a Raspberry pi 4 and multiple different Raspberry pi zero 2w’s.
Here are some possible causes and solutions:
The RFID module is sensitive to power stability, and the power provided by the Raspberry Pi’s GPIO pins may be insufficient.
Try using an external 3.3V power supply to power the MFRC522.
Also, check the connections to ensure they are secure, especially the SDA and SCK lines. (This is likely a significant cause of the issue.)
Ensure that the card/tag is held close to the reader at a vertical angle.
Keep the module away from strong electromagnetic devices such as motors and speakers.
Avoid mounting the module directly on metal surfaces.
If possible, please provide a video of the issue for us to review.
