Hi.
With python? Do you mean MicroPython? If then, yes, you can use it with micropython.

I don’t think you can connect a camera to the USB-C.

I just randomly chose that pin, but I really like the LED feedback and want to do that on another project using an ESP32-S2, but the same pin on the -S2 doesn’t light up in bootloader mode.
I can’t find a strapping pin like that other than using the USB pin’s, which I already use for … USB.

Can anybody suggest another strapping pin, on the ESP32-S2 doing the same thing?

Sounds interesting… What do you want to achieve in detail? Control the ESP32 with the Raspberry Pi? Via SPI, I2C or serial?

Thanks for sharing this info.

Here is how you can define custom pins for I2C in Arduino IDE:

int sda_pin = 6; // GPIO6 as I2C SDA
int scl_pin = 7; // GPIO7 as I2C SCL

void setup()
{
Wire.setPins(sda_pin, scl_pin); // Set the I2C pins before begin
Wire.begin(); // join i2c bus (address optional for master)
}

It’s important to call “Wire.setPins()” before “Wire.begin()”.

I2C: When using the ESP32-S3 with the Arduino IDE, these are the ESP32 I2C default pins:

GPIO 8 (SDA)

GPIO 9 (SCL)

Select these two pins like this in your sketch:
//Wire.begin(I2C_SDA, I2C_SCL);
Wire.begin(8, 9);

Serial Monitor says (this is a 0.96″ I2C OLED SSD1306 display):
Scanning…
I2C device found at address 0x3C

Hardware:
ESP32-S3-DevKitC-1: https://www.amazon.com/dp/B0D9W4Y3F3
0.96″ White SSD1306 I2C OLED Display: https://www.amazon.com/dp/B09T6SJBV5

Problem: The onboard addressable RGB LED on GPIO38 is always
on bright white. I cannot find a way to simply disable it in software.

//Wire.begin(I2C_SDA, I2C_SCL);
Wire.begin(8, 9); //For ESP32-S3-DevKitC-1 board
//Wire.begin(5, 4);
//Wire.begin(33, 32);
pinMode(rgbledPin, OUTPUT);
//pinMode(rgbledPin, INPUT);
Serial.begin(115200);
Serial.println(“\nI2C Scanner Started…”);

void loop() {
byte error, address;
int nDevices;
Serial.println(“Scanning…”);
digitalWrite(rgbledPin, LOW);
//digitalWrite(rgbledPin, HIGH);
nDevices = 0;
for(address = 1; address < 127; address++ ) {
Wire.beginTransmission(address);
error = Wire.endTransmission();
if (error == 0) {
Serial.print(“I2C device found at address 0x”);
if (address<16) {
Serial.print(“0”);

Serial.println(address,HEX);
nDevices++;

THANK YOU! I have been trying to find the default GPIO pin numbers for BOTH of the ESP32-S3 default built-in I2C ports (four pins total) for days on end. And here you have two of the four, and I tested them both with an I2C scanner utility, and they work!

Is there any way you can provide the GPIO pin numbers for the second default I2C port on the ESP32-S3-DevKitC-1 board? I do not have the ESP-IDF installed so I cannot snoop around in source and header files. And of-course the ESP documentation does not list the GPIO numbers, at least I can’t find them.

Thank You, David in Florida
