Hi, I need general guidelines whether this thing is possible and if so how: I want to create an iPhone/Android app that will receives image frames from ESP32S3 Sense(and then turns them into a video). Is it possible to just send it through BLE or will it be too slow? If yes, which format is most rec...

Hi, How can use opencv library with Micropython on esp32-cam by AI-Thinker?
I only found this:
https://github.com/0015/ESP32-OpenCV-Projects
If yes, what will be the maximum fps I will reach?
Thanks

It depends. The chip itself can go quite low, but it's usually limited by the flash chip that comes along with it. If you are building your own PCB with a separate ESP32 and flash chip that can work at a low voltage, then you can likely make it work at 2.5V. If you use a devboard or module; these a...

Thanks for the replies! According to what I saw, ESP32 still works with 2.5V. I am using a non-rechagable lithium battery due to size and price(in compare with 4.2 lithium). I might change that in the future, but for now I see no reason. The problem with putting the converter at the beginning is tha...

Hi, My goal is as said, run my system at the lowest power I can. I have an esp32, a dc-dc boost converter(from 3V battery to 3.3V) and some sensors. These are 2 schematics I am considering: 1. Powering the esp32 from the 3V battery always and the sensors from the 3.3V - is it possible and correct to...

Adding wiring diagram:
ESP32 W25Q128JV
3V3 --------> 3.3V
PIN4 --------> CS
PIN18 --------> CLK
PIN23 --------> DI
PIN19 --------> DO
3V3 --------> WP
3V3 --------> HOLD
GND --------> GND
Thanks!

Hi, I want to read/write to W25Q128JV through SPI. I am using this library: https://github.com/PaulStoffregen/SerialFlash With an example code(added at the end of message), It works fine with Arduino Nano IoT 33, but with esp32 I can't see the files or write anything to the chip. It seems to fail on...

Hi,
Is there a summary of all esp32 breakout boards(feather, m5stick etc) current consumption under deep sleep with battery/power bank?
I'm looking basically for the lowest consumption board preferably that has a grove port, that is also disabled of course when sleep is enabled.
Thanks

Hi, thanks for the answer. Iv'e read some of the datasheet and found on other sources these findings: IO0 is incharge of putting the chip in serial boot mode. meaning in order to upload a code I need to connect RX,TX(crossed from my FTDI - that is connected through USB to my computer), hold IO0 low,...

Hi, My goal is to create a pcb of my own that inclueds an esp32, which I am able to upload a code into it externally(with an FTDI module or similiar,for example this one: https://amzn.to/2SgsEiA). For this I encountered a few issues looking at the sketch: 1. Connected to 3.3v on ESP-WROOM-32 are 2 c...
