I have quite a problem with powering my SIM800L EVB like this one: link
The module keeps on resetting every couple seconds. I’m powering it with a 12V 5A wall adapter through LM2596 (The board should be powered with 5V). I also added 4700uF cap as you can see on the picture below. I can use AT commands but when I want to check AT+CREG all I get is +CREG: 0,2. Any help would be much appreciated.
Thanks in advance.
