CUBEPILOT POWER MODULE (CPM): Dual Redundant Power Solution for Cube Autopilot Systems
System Overview
Reliable power management is critical for the safety and performance of any UAV systems. Voltage instability or inaccurate battery monitoring can directly impact flight stability and mission reliability. The Cube Power Module (CPM) is specifically designed to deliver stable regulated power and accurate digital voltage telemetry for Cube Autopilot systems.
Engineered for professional UAV applications, the CPM combines wide input voltage support, precision measurement, dual redundant outputs, and a rugged compact design in a single integration-ready module.
Wide Input Support up to 14S LiPo
The Cube Power Module supports an input range of 7V to 58.8V (2S to 14S LiPo). This wide range makes it suitable for high-voltage UAV platforms systems and industrial systems. Built-in reverse polarity and surge protection ensure safe and reliable operation.
Accurate Digital Voltage Telemetry
Battery monitoring accuracy plays a vital role in safe flight operations. The CPM uses a calibrated digital front-end with I2C communication to provide reliable voltage data to the Cube Autopilot.
- Voltage measurement accuracy: ±0.1V
- Stable digital communication over I2C
- Fixed I2C address (0x42) for Cube compatibility
- Reduced noise compared to traditional analog sensing
Dual Redundant 5.3V / 3A Outputs
For enhanced system reliability, the Cube Power Module provides two independent regulated output channels:
- 5.3V regulated output
- 3A maximum current per channel
- Separate Power1 and Power2 rails
These dual redundant outputs allow reliable powering of the Cube Autopilot, improving operational safety in professional UAV systems. The regulated output ensures stable performance for flight controllers and onboard electronics.
Compact and Integration-Friendly Design
The module is housed in a CNC-machined aluminum enclosure that provides effective EMI shielding and improved thermal dissipation. Its rugged construction ensures durability in vibration-prone UAV environments.
- Dimensions: 57.5 mm × 47.5 mm × 18 mm
- Weight: Approximately 50 grams
- Operating temperature: −20°C to +85°C

Conclusion
The Cube Power Module (CPM) is a precision-engineered power management solution built specifically for Cube Autopilot platforms. With support for up to 14S LiPo batteries, ±0.1V digital voltage accuracy, dual redundant 5.3V outputs, and a compact rugged enclosure, it delivers reliable performance in demanding UAV applications.
For systems where stable power and accurate telemetry are essential, the CPM provides a dependable and professional-grade solution.
The Cube Power Module securely distributes regulated 5.3V power to Cube Autopilots (like the Orange or Purple Cube) while simultaneously transmitting highly accurate digital voltage and current telemetry to the flight controller.
Redundancy ensures continuous safe operation. The CPM provides independent Power1 and Power2 5.3V/3A channel outputs. If one power path fails, the other immediately takes over, preventing mid-air flight controller power loss.
The CPM supports a wide high-voltage input range from 7V up to 58.8V, allowing simultaneous support for everything from a standard 2S up to a powerful 14S LiPo battery in a single power module.
Unlike older analog sensors that suffer from electromagnetic noise and data drift, our module utilizes a calibrated I2C digital front-end, consistently delivering exceptional voltage measurement accuracy of ±0.1V.
Yes! Because it provides high-accuracy I2C digital data alongside a standard 5.3V regulated power rail, it is perfectly compatible with systems operating the CubePilot ecosystem and other advanced Pixhawk derivatives.
Analog signals degrade over wires and vary based on environmental noise on large multirotors. By utilizing a fixed I2C address (0x42), the telemetry arrives at the CPU as clean digital sensor data—guaranteeing perfect accuracy without noise interference.
Due to the digital measurement back-end, extreme software calibration isn't necessary! The module calculates accurate power reading thresholds instantly—saving time during your UAV setup protocols.
As a trusted integration partner, Oppila provides professional power management solutions and UAV integration accessories directly to Indian tech hubs and engineering universities, providing local fast delivery and expert deployment support.
Yes, safety is critical. Built into the integration-ready module is reverse polarity protection alongside surge clamping, shielding both the module and the autopilot from catastrophic damage during unexpected power surges or terminal mistakes.
Yes, the module is tightly housed in a rugged CNC-machined aluminum enclosure. This prevents internal flex under drone vibrational stress, vastly improves thermal heat dissipation from the 5.3v regulators, and provides robust EMI shielding.
Engineered for balance between robustness and payload, the power module weighs approximately 50 grams, measuring a compact 57.5 × 47.5 × 18 mm.
Absolutely. The dual independent switching regulators continuously output 5.3 Volts at 3 Amps separately on the Power1 and Power2 rails without overheating, sufficiently driving demanding external UAV peripherals concurrently.
While explicitly designed for premium UAV builds, the high-voltage capability (14S) and digital voltage reporting make the CPM ideal for power management on remote-controlled land rovers, aquatic automation vessels, and other remote industrial systems.
Specifically tailored for real-world environmental extremes across various altitudes, the unit operates seamlessly from a freezing -20°C up to an extreme +85°C.
Yes! The module accurately monitors exactly how many Amps are actively being pulled from your battery and pairs this with the exact voltage drop calculations—letting your system calculate remaining flight capacity flawlessly.
Mapping missions rely on critical GPS and optical payload stability. Fluctuating voltage or an autopilot brownout disrupts mapping telemetry and corrupts data points. High accuracy modules secure dependable data collection.
Yes, dependent on your payload and thrust current limits, the Power Module system supports reliable high-current connectors generally installed between your battery and drone power distribution system.
The UAV sector demands increasing payload sizes via high-voltage battery arrays (like 12S and 14S sizes) that scale beyond aging analog hardware measurement constraints. I2C Digital voltage sensing solves these accuracy and scaling problems instantly.
Frequent unexpected failsafe triggers, mid-flight reboot brownouts, glitching camera gimbals, or drastically wrong battery percentage displays inside QGroundControl or Mission Planner are key signs you need to upgrade to a digital Power Module.
Assuredly! Oppila provides specialized industrial integration. We take premium modules like the CPM, Carrier Boards, Jetson modules, and multi-axis camera arrays, mapping them flawlessly into your custom aerial robotics chassis design.
