OpenTurbine 2.0 · open-source ESP32 turbine ECU

Build the turbine controller your system needs

Configure sensors, actuators, sequences, limits and control rules from a browser. No source-code build is required for the normal Windows setup.

Download for Windows Get started

Normal Windows setup does not require Git, PlatformIO, or source-code compilation.

For turbojets, APUs, generators, turboshafts, turboprops and turbine test rigs.

What it provides

One configurable ECU platform

OpenTurbine describes the hardware actually fitted to the engine, exposes the relevant settings, and keeps unrelated options out of the way.

Editable startup and shutdown sequences
Sensor calibration and actuator testing
Speed, temperature, pressure and controller limits
Native, SPI, OneWire and discovered I²C sensor hardware
PCB-profile ports, torque/thrust load cells and oil-flow monitoring
Threshold and input-to-output control rules
Browser monitoring, backups, event logs and run logs

Check compatibility before installing

Normal setup supports Classic ESP32 boards with at least 4 MB flash and ESP32-S3 DevKitC-1-compatible boards with at least 8 MB flash. The universal S3 image also runs on 16 MB modules and does not require PSRAM. The guided installer currently requires Windows.

Experimental software, independent safety

OpenTurbine does not replace suitable drivers, fusing, signal conditioning or an independent physical emergency stop. Verify the complete system with fuel, ignition energy, starter power and load power isolated before an operating test.
