- Live simulation. The solver runs while you build, and the current flows along the wires.
- Real SPICE too. ngspice is built in, and the two solvers can be compared on the same circuit.
- Instruments. Oscilloscope, multimeter and an 8-channel logic analyzer.
- Analysis. AC sweep with a Bode plot, Monte Carlo tolerance runs and a SPICE linter.
- Microcontrollers. ESP32, RP2040 and STM32 with a serial monitor, an OLED, an LCD and a motion sensor.
- Co-Pilot and MCP. An AI assistant in the app, and an MCP server so other tools can read and edit the circuit.
- Parts and export. A bill of materials with prices, KiCad export and OpenSCAD enclosures.
- Academy. Lessons about electricity and electronics.
Windows 10 and 11.
