I just completed another board explorer web app - this time for the ESP32 Devkit V1 board- ESP32 Pinout Explorer - Interactive Free Web App. This is ESP32 DevKit V1 interactive pinout diagram were you can click any pin to see analog, digital, PWM, communication interfaces and technical specs is a free maker tool. I had previously created the Arduino Pinout Explorer web app, and having that experience made building this version much easier and faster. I told about the experience in my previous post I built Arduino Uno Pinout Explorer. With this new tool, users can instantly see which pins to use for their projects. There are several advantages to using this web app:
First, when planning larger projects where pins and functionality are limited, it's crucial to plan ahead. You need to decide which pins will handle sensors, ADC readings, external communication via SPI, PWM for motor control, and more. This tool helps you visualize and plan all that before you start wiring.
Another advantage is that it's useful for both beginners and professionals alike. Even experienced developers sometimes need to double-check pin functions or refresh their memory. This web app serves as a quick-reference datasheet - and with some future improvements, it could become even more comprehensive.
The following video is a demonstration of this web app.
