I have been using NANO’s for years as most projects are very simple, however I had a need to 3.3v logic levels so made the leap and bought 3 x ESP32-S3 (Amazon) and wow, lots of setup and not what I’m using to (simple load and go) I programmed all 3 of the ESP’s with the example “getchipid” code after installing the github board packages. all three keep rebooting (output below) so I am 99% it’s just a setting or me, any pointers would be much appreciated.

Rebooting...
What does that mean, when I get a new esp32 I just selct the board type from the list and it works.
That is really confusing. The normal procedure is
NO additional URL is needed. Just go into the board manager and enter esp32 in the search box, click install as seen below.
OK I probably got overwhelmed and tried to google too many things, I have gone back to basics and as you say I’m now using as you say the provided ESP32 board, there are lots of examples but I want a simple blinkled type example, whats the most basic example you know that will simple prove I have everything setup ok? I’m assuming I can’t use “blink” as when I tried it nothing happened. (p.s. if does seem to have stopped rebooting thx)
Hi, I’ve checked the link and it goes to “diymore 3PCS ESP32-S3 WiFi Bluetooth Mini Development Board Module Dual-Core Processor Based on ESP32-S3” on amazon”
I have also uploaded this simple code and got no output in serial monitor set to correct speed.
void setup()
{
Serial.begin(115200);
}
// void loop runs over and over again
void loop()
{
Serial.println("Hello world");
delay(1000);
}
I selected the ESP32-S3 that’s what was in the Amazon advert. (see picture attached)
Is there a full list of all the chip setting I should use, I did change some after watching various video’s / google articles. so I want to make sure these are all OK as its still not working.
Wrong setting in Arduino IDE. Disable octal PSRAM. If you have PSRAM it should be QIO. Or may be you don’t have any. Also wrong setting of the flash size. Arduino IDE→Tools→PSRAM and Arduino IDE→Tools→Flash Size
Looks like you bough low end version. Common s3 devboards are 16mb flash and 8mb octal psram. Yours is 4mb flash and I think, no PSRAM at all. Did you set you target to ESP32S3 Dev Module?
We have lift off :-) thanks everyone especially Jim, I did as you said in post #12 but as I din’t have a LED attached did the Hello world and it worked. thanks again, I’m sure I will be back lol.
Worked a treat :-) I think coming from a simple Nano this is what is causing my confusion, the plethora of settings/board types. maybe I bought the wrong board for a beginner to ESP32! is there a board that’s much more widly used or even better, an Arduino version? as theoretically this would be popular well supported, I’m only looking for a simple board hence picking this little one I have as I’m trying to attached a RD-03D so only need Tx/Rx and a couple of other I/O.
