There is a bare chip ESP32-S3-PICO-1-N8R2 that has in-package 2 MB SRAM and 8 MB flash. Are there plans of creating a MINI module out of it?

In the documentation, it says it's ok to power down flash using: esp_sleep_pd_config(ESP_PD_DOMAIN_VDDSDIO, ESP_PD_OPTION_OFF); If the rtc timer is not set as wake source *or* the sleep timer is long enough. Lifted verbatim from the docs: Calling esp_sleep_pd_config(ESP_PD_DOMAIN_VDDSDIO, ESP_PD_OPT...

Another update, I think I've managed to reach the theoretical light sleep current mentioned in the datasheet: https://i.ibb.co/Kb5TH3n/lowest-light-sleep.png This was achieved in the following conditions: - kconfig: enable PM, enable tickless idle, enable flash power down - configure pm with auto li...

Ok, this seems to be related to some current leakage to the flash. If flash *is* powered down, the light sleep current remains at ~700 uA.
Though, is the leakage current expected to be that high (difference of ~1.1 mA), even with the workaround Kconfig option enabled?

Hi, I'm looking into my custom board's light sleep current consumption. I'm expecting well below sub-1mA, given ESP32-S3 240 uA light sleep current (claimed on the datasheet) + quiescent current draw from components on-board which I estimate to just be a few hundred uA. I've used the light sleep exa...

I made a showcase video for the ESP32-S3 PowerFeather: https://youtu.be/VF9AFk1Hf88

Since the release of ESP32-S3 PowerFeather I’ve been working on a demo web app that lets users explore some of the features of ESP32-S3 PowerFeather, which I recently got to a decent state: https://i.ibb.co/WWMsGxT/charging-current.jpg The web app is served from the ESP32-S3 PowerFeather (acting as ...

Hello, it's been a few months. But perhaps you might be interested in ESP32-S3 PowerFeather (https://powerfeather.dev/)?
Full disclosure, I'm the creator of the board.

Hello all, I want to introduce ESP32-S3 PowerFeather, a dev board that should make it a little easier to create solar + Li-ion/LiPo powered projects! It uses a charger IC that's smarter than most other similar boards: Texas Instruments BQ25628E; and also has an on-board LC709204F fuel gauge. Deep-sl...

I have found a bizarre behavior, and I was wondering if anybody can reproduce this on ESP32-S3-Devkit-C-1 v1.0 and ESP-IDF v4.4.6. I built and flashed an application with the following main code: void app_main(void) { static RTC_NOINIT_ATTR uint32_t test; printf("test: 0x%08x\n", test); test = 0xdea...
