About
Wokwi is an online electronics simulator that lets users simulate microcontrollers and embedded systems—including ESP32, Arduino, STM32, and Raspberry Pi Pico—directly in a browser. It supports WiFi simulation, virtual logic analyzers, GDB debugging, and custom chip design. A Classroom tier serves universities and organizations, and a Tiny Tapeout integration enables users to turn digital circuit designs into real silicon chips.
Problem
Setting up physical hardware for IoT and embedded development is expensive, slow, and risky—components can be damaged or unavailable.
For
Electronics hobbyists, makers, students, and embedded systems developers
How it works
Users build and code virtual electronic circuits in a browser-based simulator that supports real microcontroller environments, WiFi, and debugging tools without any hardware required.
