🖥️ How to Use the ESP32 DevKit V1 Pinout Tool
1. Navigate the Pin Map
The ESP32 DevKit has dual cores and many GPIO pins with multiple functions.
Hover or click on pins in the diagram to see their role (digital I/O, ADC, DAC, PWM, touch sensing, etc.).
This helps you plan which pins to use for sensors, actuators, or communication modules.
2. Understand Special Functions
The tool highlights pins with Wi‑Fi, Bluetooth, and capacitive touch capabilities.
Some pins are input‑only or have restrictions — the explorer makes these clear so you avoid wiring mistakes.
3. Check Power Pins
The diagram shows 3.3V, VIN, and GND pins.
Remember: ESP32 is a 3.3V device — connecting 5V signals directly can damage it.
Use the tool to confirm safe voltage levels for external modules.
4. Explore Communication Interfaces
The ESP32 supports multiple UARTs, SPI buses, and I2C channels.
The explorer shows which pins can be remapped for these functions, giving you flexibility in design.
5. Plan Advanced Projects
With built‑in Wi‑Fi and Bluetooth, the ESP32 is ideal for IoT.
Use the tool to decide pin assignments before coding, especially for projects with displays, sensors, and wireless communication.
6. Educational Use
Teachers can use the tool to demonstrate how modern microcontrollers integrate wireless features.
Beginners can visually grasp the difference between ESP32 and simpler boards like Arduino Uno.
✅ Why This Tool Is Useful
Simplifies working with a feature‑rich microcontroller.
Prevents wiring errors by showing pin restrictions.
Helps plan IoT projects with Wi‑Fi and Bluetooth.
Acts as a quick reference while coding and prototyping.
