SkyPulse Helios FMU: την πλήρη αναφορά
Overview
Flight control and companion compute, unified.
Helios combines a sensor-redundant flight controller with a Raspberry Pi Compute Module 5 companion computer in a single integrated module. Triple IMUs, a dedicated compass, and centimeter-level barometric sensing feed deterministic control, while the onboard CM5 runs Debian Bookworm with PCIe expansion for AI accelerators. Native ArduPilot and PX4 support keeps the platform open and field-proven across hundreds of flight hours.

Known limitations
- Direct 8S connection requires external protection
- For systems up to 6S, direct battery connection is typical. Direct 8S connection requires an external filter or protection circuit because of inductive motor spikes.
- 36 V is the documented maximum input
- Above 36 V, use a BEC with adequate current capacity. Because Helios can draw approximately 12 W at full load, the documentation recommends a BEC capable of delivering more than 20 W to preserve headroom.
- J5 polarity is not reverse-protected
- Reversing J5 polarity will damage the unit. Verify polarity before every power-up.
FAQ
What firmware does Helios support?
Helios fully supports ArduPilot and PX4. Custom firmware builds are also supported. Helios FMUs ship with ArduCopter by default; PX4 can be flashed via USB.
What companion computer does Helios use?
Helios integrates a Raspberry Pi Compute Module 5 (eMMC variant) running a clean Debian Bookworm image, with 4x Arm Cortex-A76 cores at 2.4 GHz, up to 8 GB RAM, and up to 64 GB onboard eMMC.
Can I run AI workloads on Helios?
Yes. The companion computer supports TensorFlow, OpenCV, ROS, and other applications from the SkyPulse software stack, and PCIe on the J3 Interface connector is available for AI accelerators.
How do I power Helios?
Helios accepts up to 36 V via the J5 Molex Nano-Fit connector. Direct battery connection is typical for systems up to 6S. For direct 8S, an external filter or protection circuit is required due to inductive motor spikes. For systems above 36 V, use a BEC capable of delivering more than 20 W. Always verify J5 polarity before power-up — reversing polarity will damage the unit.
What connectors does Helios use?
J5 is a 2-pin Molex Nano-Fit locking connector (45130-0201) for power. J1/FMU1 and J2/FMU2 use Molex Pico-Clasp 501189-3010 connectors for flight-controller interfaces. J3 provides companion-computer interface signals (Ethernet, USB, PCIe), and J4 exposes additional GPIO, USB, and UART signals.
Is Helios NDAA compliant?
Yes. 100% NDAA compliant, built on high-quality non-Chinese components.
