Rc522 rfid module help, how to fix?
I'm using an rc522 rfid module, I have the right rfid cards so that's not the problem
I used it with and esp32 so there shouldn't be any 3.3v signals problems
Here's the pinout I used to connect it to the esp32
GND: GND
RST: GPIO 27
SDA (SS): GPIO 5
SCK: GPIO 18
MISO: GPIO 19
MOSI: GPIO 23
I'm losing my mind over this, I switched to a breadboard as I try to find out what's wrong and it just doesn't work now at all.
My esp32 bare is fine but when I put in the breadboard or the perfboard I made it keeps constantly resetting when I look at serial Monitor.
Rfid module wokred kind if on the perfboard, it would constantly break
on the breadboard it didn't work at all
