Since my test on F8R2 failed on my S3 boards, I decided to test the official S3 Dev board made by Espressif.
At first I made sure that both USB native and USB to UART ports would work. I could upload the Blink-A-LED and an external LED flashed as I expected.

Then I removed the metal cover on the ...

Hi All,
Does anybody know where I can buy an ESP32-S3-PICO-1-N8R2 Dev. board? The controller was available 6 months ago. See the link at reddit. https://www.reddit.com/r/esp32/comments/12d8b7j/is_the_esp32s3pico1_real_i_dont_see_it_mentioned/

The controller is available at DigiKey now. https://www ...

I recently made ESP32-S2 and S3 prototype boards with the long Reset Press feature. It worked as I expected, so it can work on your boards as well.

See the video clip at https://www.smallpico.com/LRP_button.mp4

A short reset press will run the sketch, you can see the LED at the up right corner ...

A while ago I came across a message about finding internal pull-up resistance of the ESP32, but I don't remember when.

It is not difficult to do. No calculation is needed.

To enable internal pull-up on an IO pin such as GPIO04, add the following line of code in your setup() function.

pinMode(4 ...

Sorry for the missing picture.

Hi All,
It seems quite a few people are interested in this circuitry. So I would like to show my final circuitry, and the cost can be reduced for putting it into your board.

Below is the low cost version. You can use one of 3 buffers, HC1G50, HC1G08 and HC1G125, so you can always find one.
Do not ...

Hi All,
Why do most ESP32 boards, including the TinyS2, TinyS3, FeatherS2 and FeatherS3 have 2 buttons for reset and GPIO00? Sometimes two buttons are very close and it's very hard to push with two big fingers. I think that the problem can be solved by using the reset button with a hardware timer. A ...
