Thank you for the links. They do indeed have a lot of options but sadly they quickly dry up when I select United Kingdom.

I guess I'll have to do some experimentation with products I find on Amazon.

Any reputable 5v-5.1v 1A wall wart will be fine.

That's what I've read in the HUZZAH32 documentation, yes. But the trouble is that there aren't many reputable 5v-5.1v 1A power supplies available on the market.

Would a 0-2.4A self-regulating unit work well?

I have a few ESP32 (Adafruit HUZZAH32) that I would like to power from the main supply. I'm looking for something reliable that won't burn the house down in the long term. Before I go on a shopping spree, I would like to know what should work best: - RPI power supply (5.1V 2.5A or 5.1V 3A) - Anker (...

Silly me, I should have thought about that, thank you. The voltage seems fine. ~5.2V on USB and ~3.3 on 3V. When `gpio_deep_sleep_hold_en()` is called the voltage is about the same in deep sleep too. The hilarious part is that everything suddenly started working. One thing I've changed is that I've ...

I do, but you'll have to tell me where to measure

I power the RPI 4 with the Official UK Raspberry Pi 4 Power Supply (5.1V 3A). The RPI 3B has an official power supply as well.

Is anything apart from the LED and the BME680 connected to the HUZZAH32? Which pin(s) are in use? There's nothing else. The BME680 is connected via SCL/SDA, the LED via A1 (GPIO #25). Actually it's not only that one specific situation. When, on another HUZZAH32 board, I try to write to an SD card u...

The board works just fine when it's not using much power. I have a BME680 connected to it that saves it's state into RTC. There's also a LED that's usually off. All works fine at this point. But when the LED is turned on, `gpio_deep_sleep_hold_en()` is called and the board goes into deep sleep for ~...

I'm trying to power my HUZZAH32 by connecting it to a Raspberry Pi 4 USB port. It's the only connected device, other the Raspberry Pi fan that's tied to a 3v pin. I'd like to do this just so I avoid having yet another power prick laying around. My ESP 32 board works perfectly fine when powered by a ...

I'm hoping to be able to read the USB battery voltage so that I can predict when it's about to run out of juice.

For ESP8266 I've found https://github.com/micropython/micropyt ... -242315810 to work nicely. Is there something similar for ESP32?
