VME290 deep sleep

#1

Quick question in case someone has already measured this. When putting the VME290 into deep sleep with the standard esp_deep_sleep_start call, does that power down everything or are other GPIO pin settings needed. Afaict the schematic doesn’t indicate any other circuitry that I’d need to worry about (e.g., display).

My next step is to actually measure the deep sleep current and then will report back.

Looks like I’m getting 700uA during deep sleep, seems a bit high - would have expected 20-100uA.

I haven’t measured my VME290 yet, but all other ESP32-S3 boards can get ≤25uA. Things to check are whether the radio is asleep (if it’s on your board), if there’s anything connected by any chance, and if you use any wakeup sources other than timer wakeup.
