I designed a custom PCB to run the ESP32 on battery for long time.Problem: The deep sleep current is way to high.
I reduced it to the following setup:
When using the deepsleep mode by either flashing my own software which calls:
Code: Select all
esp_sleep_enable_timer_wakeup(MAIN_CFG_TIME_TO_SLEEP * uS_TO_S_FACTOR); esp_deep_sleep_start();
I have no clue why this is happening. I tried several of my PCBs, multiple ESP32, I removed the LDO and tried to power by bench power supply and by battery. The bench supply shows roughly the same amount of current being drawed.

What did I miss? What should I try to find a solution?
With this link you can see the PCB and schematics of 1) the complete project and 2) the reduced setup for testing purposes
