• Temperature PID control

• Motor, pump, and glow plug control

• Serial telemetry via Fusain protocol

• Safety interlocks and fault detection

Architecture

Helios uses Zephyr’s Zbus for inter-module communication:

• State Machine - Main operational logic

• Temperature Controller - PID-based temperature regulation

• Motor Controller - Combustion air blower control

• Pump Controller - Fuel pump control

• Glow Controller - Igniter control

• Serial Handler - Fusain protocol communication
