About Us

ICExplorer.online is a free, interactive web tool designed for electronics engineers, hobbyists, students, and makers who need quick access to integrated circuit (IC) pinout information.

Our platform provides a visual, clickable IC explorer that lets you:

Explore IC Pins Interactively – Click any pin to view detailed specifications, voltage ratings, current limits, and functional descriptions.

Filter Pins by Function – Quickly identify pins by their roles: PWM, ADC, USART, SPI, I²C, Camera Interface, USB, Timers, GPIO, Comparator, Reference Voltage, Oscillator, Power, Ground, and more.

Access Design Files – View schematic symbols, PCB footprints, and block diagrams for each component.

Upload & Analyze Datasheets – Upload PDF datasheets to extract key specifications automatically.

Learn by Exploring – Perfect for beginners learning microcontroller pinouts or professionals cross-referencing components.

We currently support popular microcontrollers and timer ICs including:

PIC Microcontrollers (PIC12F683, PIC16F877A, PIC18F4550, etc.)

AVR Series (ATmega328P, ATmega32, ATtiny13, ATtiny45)

ESP32 (Devkit V1, ESP32-CAM)

MSP430 (G2553, F5529, FR5994)

Classic ICs (NE555 Timer, TL494 PWM Controller)

More ICs are being added regularly.

As electronics enthusiasts ourselves, we understand the frustration of digging through hundreds of pages of datasheets just to find a single pin function. ICExplorer.online was created to make this process faster, more visual, and enjoyable. No more squinting at tiny PDF pinout diagrams – just click, explore, and learn.

To provide the world's most accessible, interactive, and comprehensive IC reference tool – completely free for everyone. Whether you're designing a PCB, debugging a circuit, or teaching electronics, ICExplorer.online is here to help.
