Tried different-10,47,100,470uf. I suspect something is wrong with the 5v pin as it's the same when I tried a breadboard stable 5v power supply. It's strange because the USB is working.

Hello,
I'm trying to power my board using HLK-PM01 220V to 5V power module. The board enters in bootloop if the PS is connected to the 5V pin. It works if powered from USB but ONLY if the PS is not connected to the 5V pin. Tried some caps on the PS output but didn't help.

Thanks for the replies. So its most probably the quality of the Doit esp32 board.

Well, i found the problem. I've used the esp_netif_t type in a wrong way. Now i have another problem, i cant link anything from esp_netif . The linker complains against anything netif related: /home/anio/.espressif/tools/xtensa-esp32-elf/esp-2019r2-8.2.0/xtensa-esp32-elf/bin/../lib/gcc/xtensa-esp32-...

I just changed to v4.1 and my project is a complete mess now :) I am looking in the compilation errors and replacing 1 by 1 but it's a pain. It's hard to search in the documentation because I don't know what to search for. It might be good if you write some article about it because this is a big cha...

I cannot understand this porting to Arduino at all. Why people want to wrap everything in Arduino environment?

Have anyone tried SP6205EM5-L-3-3 or MCP1726-3302E/SN?
