The Cube Purple – Module

The Cube Purple – Module is a compact, simplified version of the Cube Black autopilot, built around a single IMU and barometer instead of a triple-redundant sensor stack. That makes it ideal for ground and surface vehicles — cars, rovers, boats, and smooth fixed-wings — where space matters more than flight-grade redundancy. It runs the same STM32H753 flight management unit as its bigger siblings and connects through the standard 80-pin DF17 connector, so it drops straight into any CubePilot-compliant carrier board.

The Cube Purple – Module Packs Serious Autopilot Power Into a Tiny Case

The Cube Purple – Module is a smaller, simplified version of the Cube Black, built around a single IMU and a single barometer instead of the triple-redundant sensor stack found on Cube Black and Cube Orange+. That makes it the right choice when you don't need flight-grade sensor redundancy and want to save space and weight instead — smooth fixed-wings, rovers, boats, and other ground or surface vehicles. Despite the smaller footprint, The Cube Purple – Module still runs the same STM32H753 flight management unit as its bigger siblings, so you get a genuinely capable, reliable autopilot in a compact case.

Key Features of The Cube Purple – Module

Compact single-board design
FMU and IMU housed in one small case — Cube Black's flight-management power, without the second and third IMU board.

Built for ground and surface vehicles
Purpose-suited for cars, rovers, boats, and smooth fixed-wings that don't need vibration isolation.

Powerful STM32H753 processor
2MB flash, 1MB RAM — the same FMU family used in Cube Orange.

Standard DF17 connector
Plug-and-play with any CubePilot-compliant carrier board, including the Mini Carrier Board.

Frequently Asked Questions About The Cube Purple – Module

The Cube Purple – Module uses a single IMU and a single barometer built directly onto the flight management unit, instead of the separate vibration-damped IMU board and sensor redundancy found on Cube Black and Cube Orange+. This keeps the case smaller and lighter, at the cost of the sensor redundancy those boards offer.

No — because it has a single, fixed IMU rather than a vibration-damped sensor board, The Cube Purple – Module does not require external vibration isolation. Before choosing it, just confirm your application doesn't rely on the vibration damping that Cube Black/Orange+ provide.

No. As of 27 August 2026, The Cube Purple – Module is sold without a microSD (uSD) card. If your configuration needs one, order it separately.

The Cube Purple – Module uses the same 80-pin DF17 connector as the rest of The Cube family, so it works with any CubePilot reference-design carrier board — including the compact Mini Carrier Board, a natural match for Cube Purple's smaller size.

I/O and Connectivity on The Cube Purple – Module

The Cube Purple – Module shares the same I/O layout as the rest of The Cube family:

14 PWM servo outputs (8 from the I/O chip, 6 from the FMU)
R/C input for CPPM, Spektrum/DSM, and S.Bus
S.Bus servo output and an analog/PWM RSSI input
5 general-purpose serial ports, two with full flow control
2 I2C ports and 1 SPI port
2 CAN Bus interfaces
3 analog inputs
Safety switch/LED and a high-power RGB LED driver
