PicoV3 - Arduino ?

Short question: Can I also use the ESP32-PICO-V3 chip with Arduino? Does it work exactly like the ESP32-PICO-D4, or with special settings, or not at all?

Hello, can anyone give some information about it?
I don't mean the ESP32-picoV3-2, which is currently only available as a sample.
I mean the simple ESP32-picoV3, which has been produced and sold normally for some time.
Thank you.

See section "3.3 Compatibility with ESP32­PICO­D4" of PICO-V3 datasheet:
https://www.espressif.com/sites/default ... eet_en.pdf

If GPIOs 18 and 23 are defaults for any of the Arduino functionality (eg. I2C bus) then you might have issues with libraries that expect those pins. Otherwise it should be fine. Have you tried it?

I don't see any problem adapting special GPIOs (e.g. 18/19 for I2C), that should work. My question is first: Can I create a program via Arduino and program it into the chip so that it works?
No, I haven't tested it yet, but ask beforehand ;)
I intend to create a board where I've used the pico-D4 so far. I do not need a possible memory expansion and would also like to use the new chip pico-V3. But Arduino is used for software creation, hence my question.

Since it is not possible to get such a simple answer in advance, I have to test it myself :(
It is comparable to the first step of mankind on the moon, nobody has programmed this chip with Arduino before.

Hi,

You can use it without any problems. The ESP32-PICO-V3 has the same core as the ESP32-D0WD i.e plus internal flash memory and the 40MHz crystal. The V3 stands for the ECO V3, with some wafer-level changes. See the document for more information.

I hope it helps you!

Thanks.
That's exactly how I thought it, just wanted to be assured by a professional that it really is.
The answer was that simple and quick. Thanks again.
