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.d...

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 will ...

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, INPU...

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 us...

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...
