Thank you tlfong01 , I learned a lot today. Thanks to you. Sorry for late message, I wasn't on computer. I will "check it out by experimenting ".

In that link, they use 2N3904 but I couldn't find it in my shop so I am using 2N 2222. Thank you for your great knowledges. Have a nice day, cheers.

@tlfong01, thank you. First I actually use this [relay] (forums.raspberrypi.com/download/file.php?id=49019) but when I use this on GP14, W5500 isn't working even 1 or 2 min. It is disconnecting immediatelly. Now I tried this on another pin GP28 (I will change it don't worry, I will use GP23 or smt that not Analog pin) , It is working good. So I guess the problem is really GP14 pin. I guess I shouldn't use it when I use SP1.

@tlfong01 Sorry I didn't mention it before. I added pins, w5500 , relay module and connections on question. I am using banggodlink this and SPI1.

No, I didn't move or didn't change anything on relay. Only I changed pin14 to pin28, and it is working. I tried to connect pin14 again to see what will happen, It gave error again.

@user263983 I have electrolytic capacitors but I don't have minimum 10mkF . I have micro Farads and Nano Farads

I have 3 ceramic caps but I don't know the values. (Top of the cap says (56,102,271))

user263983 I will buy tantal (ceramic I guess) caps tomorrow , I don't have for now.

@user263983 I don't have it

@Tyler I did it .

@Bimpelrekkie I am giving Pico's 5V to Lm1117 Vin (Pico's 5V give 200mA). Vout gives 3.28 V and 92mA but I need a 3.3V 180mA to Esp01 work. I am using regulator first time I don't know, I read LM1117 gives 800mA that's why I bought.

@user263983 ceramic 20 µF to where ? Vin and ground side ? is it enough ?

@Kartman Vin gives 185-205 mA VOUT gives 90-98 mA, I make caps conenction 10 µF for Vin , 100 µF for Vout

@user263983 I am using 10 µF for Vin , 100 µF for Vout

@JRE here is my lm1117 direnc.net/lm1117-ld1117-3v3-ayarli-regulator-33v-to220 , I am taking power from computers USB port .

@Bimpelrekkie When I measure VIN it gives 200ma. What would u suggest to get at least 200ma
