The Aleph Drone Expansion Board is a versatile, standalone flight controller built around the high-performance STM32H7 microcontroller. Designed for seamless integration into drone and robotics systems, it features a flight sensor suite, exposed communication peripherals, and an onboard debugger/flasher accessible via a single USB-C connection—streamlining development and deployment. 

This open development platform supports popular autopilot firmware such as PX4 and Betaflight, as well as Elodin’s own Roci control stack or any custom flight software. For compute-intensive missions, it can interface directly with the Aleph Carrier Board, enabling tight coupling between low-level control and high-level autonomy.

This flight controller board is NDAA-compliant and manufactured in the USA.

Intelligent Power Architecture

  • Direct battery input

    (4S–6S) with onboard regulation — no need for an external 5V PDB

  • USB-C PD support

    For powering the board during development or bench testing

  • Switchable, isolated 5V auxiliary rail

    • Peripherals (e.g., GPS, radios, rangefinders)
    • Protected by an eFuse with reverse current protection to prevent misbehaving devices from affecting main board power

  • Voltage and current monitoring

    On key power domains for fault detection and diagnostics

Ready for Real Systems

  • Comprehensive I/O

    • 3x UART
    • 2x CAN
    • I2C
    • 16x PWM
    • 8xGPIO
    • USB FS
    • microSD

  • Full flight-ready sensor suite

    • 3× IMUs
    • Magnetometer
    • Barometer

  • Standard JST-GH connectors

    Supporting all typical drone peripherals: GPS, ESCs, RC receivers, telemetry modules, etc.

  • 7 status LEDs

    For system visibility and debugging

Modular and Flexible

A high-speed board-to-board connector allows the Aleph to slot into a wide range of system architectures:

  • As a standalone flight controller with PX4, Betaflight, or Elodin’s Roci flight software stack
  • As an expansion module paired with a compute board (e.g. Aleph Orin Carrier), offloading low-level control while enabling high-level autonomy
  • As a core control module in scalable, modular system that’s ideal for custom robotics platforms, drone swarms, or tightly integrated compute + control stacks

This board is NDAA-compliant and manufactured in the United States. Its combination of reliability, modularity, and developer experience makes it a strong foundation for advanced UAV and robotics systems.
