The ESP32-S2-MINI-2 module doesn't have default pins explicitly labeled as SDA (data line) and SCL (clock line) for I2C communication. However, you can configure any GPIO pin to be the SDA and SCL with the ESP32 family of microcontrollers. Here are some guidelines:

  • SDA (Serial Data Line): Typically corresponds to GPIO21 (but any available GPIO can be configured).

  • SCL (Serial Clock Line): Typically corresponds to GPIO22 (but any available GPIO can also be configured).

In your project, here are some potential candidates based on the GPIO pins you're using:

  • GPIO1, GPIO2 are common choices for I2C.

  • GPIO36 can be used as a branch point.

  • GPIO21 for SDA (since it is typically configured as such).

To configure these pins in your code, you typically use the Wire.begin(SDA, SCL) function in the Arduino IDE or equivalent function if you're using another development environment. Here is a brief example of how you might do this:
Cpp
#include <Wire.h>

#define SDA_PIN 21  // Change as per your choice
#define SCL_PIN 22  // Change as per your choice

void setup() {
  Wire.begin(SDA_PIN, SCL_PIN);
}

void loop() {
  // Your code here
}
You can choose any GPIO that is free in your current design:

  • SDA Example: Connect GPIO21 to SDA.

  • SCL Example: Connect GPIO22 to SCL.

If you would like to assign specific GPIOs already in your design, feel free to let me know which pins and I can suggest exact schematic connections.

Hey, I’m Copilot, your AI design assistant. I can help you brainstorm ideas, debug problems, research components, and even make wiring connections for you. Ask me questions like:

  • @copilot I'm designing a PCB for a medical device that measures heart rate and temperature. Can you give me the list of components I will need?

  • @copilot How would I connect these parts to make the LED flash at 1kHz?

  • @copilot can you choose 4 digital pins on the ATMega328P-AU that I have here to use as GPIO given that I am already using some pins for reset, the external clock, UART, and I2C.

Chat with me by tagging @copilot on comments or in the chat.
