I think it's easier to see as a table: By mentioning Arduino I mean atmega328p-based Arduino. Of course, there are any other MCU used, I'm just giving a context.

Could you show us your schematic? I don't know what's happened, but putting an external pull-up resistor to GPIO0 should make things better.

Try to remove those decoupling capacitors temporarily and see if it's improved your current consumption, sometimes faulty caps have unacceptable current leakage for low power environment. I built a minimal setup for ESP32 and I can easily achieve sub 10uA (around 2.5uA to be precise).

No update on this?

Recently Electrodragon started selling IPS6404L-SQ-SPN (priced only 0.8 US$ !), a SPIRAM (psRAM) chip (8MB) with characteristics similar to Espressif's ESP-PSRAM32 ( Data sheet ). As this is a 3.3V device , it can be used with ESP-WROOM-32 and all boards using 3.3V Flash . I've tested the chip on A...
