Pin Configuration and Descriptions

Note: The above table is a simplified representation. Each GPIO pin has multiple functions, and the exact pinout should be referred to from the ESP32 datasheet or pinout diagram provided by Espressif.

Usage Instructions

Integrating with a Circuit

1. Powering the ESP32-DEVKIT-V1: Connect a 5V power supply to the micro USB port or supply 7-12V to the Vin pin.
2. Connecting to a Computer: Use a micro USB cable to connect the board to a computer for programming.
3. GPIO Pin Usage: Refer to the pinout diagram to understand the multiplexed functions of each GPIO pin.
4. Programming: Use the Arduino IDE or other supported IDEs to program the ESP32. Ensure you have the necessary board packages installed.

Best Practices

• Always use a voltage regulator when supplying power through the Vin pin to prevent damage.
• Avoid drawing more than 12mA from any GPIO pin.
• Use external pull-up or pull-down resistors with GPIO pins when required.
• Ensure that the antenna area is clear of metal components to avoid signal interference.

Example Arduino Code for ESP32 Module

// Simple Blink example for ESP32-36PINS-DEVKIT-V1

#define LED_BUILTIN 2 // Define the LED_BUILTIN pin. It’s usually GPIO 2

void setup() {
pinMode(LED_BUILTIN, OUTPUT); // Initialize the LED_BUILTIN pin as an output
}
void loop() {
digitalWrite(LED_BUILTIN, HIGH); // Turn the LED on
delay(1000);                     // Wait for a second
digitalWrite(LED_BUILTIN, LOW);  // Turn the LED off
delay(1000);                     // Wait for a second
}
