SPICE Circuit & ESP32 Simulator is a circuit editor and simulator that runs on SPICE engine for solving circuits.

SIMULATE LIKE A PROFESSIONAL TOOL
• DC operating point: node voltages and branch currents
• DC sweep, AC frequency response and transient analysis
• Mixed mode- Analog and digital circuits in the same simulation

REAL MANUFACTURER MODELS
Go beyond ideal parts with SPICE models of real devices, including:
• Operational, instrumentation, audio, video and current-sense amplifiers
• BJTs, MOSFETs, IGBTs, diodes, Zener, Schottky and LED models
• Voltage regulators, DC-DC converters, comparators and timers
• ADCs, DACs, analog switches and 74xx logic
• Optocouplers, relays, motor drivers and power modules

MICROCONTROLLER SIMULATION
Add an ESP32 board, write a program in the built-in code editor (MicroPython), and watch it drive the rest of your circuit. LEDs, buzzers, servos, 7-segment displays, LCD and OLED screens, rotary encoders and sensors respond on the canvas.

AI CIRCUIT ASSISTANT
Ask questions about your design, get explanations of how a circuit works, and get help writing microcontroller code.

SAVE, OPEN AND SHARE
• Save projects on your device and open them any time
• Sign in to keep your circuits in the cloud.

WHO IT'S FOR
Electronics students, hobbyists, makers and engineers who want to try an idea, check a design or understand a circuit without a desktop computer.

FREE AND OPTIONAL PURCHASES
The editor, simulator and standard component library are free to use, with a daily allowance of AI messages and no ads. Optional in-app purchases unlock the full real-model component library or a Pro subscription with more AI messages. You can use the app as a guest, or sign in to save to the cloud.
