CubeNode ETH – Ethernet Adapter for CubePilot Flight Controllers

The CubeNode ETH is a compact networking adapter by CubePilot, designed to add 10/100 Mbps Ethernet connectivity to Cube flight controllers lacking native support. Powered by dual-core Arm® Cortex® M7 and M4 processors, it runs at up to 480 MHz and 240 MHz respectively. With support for PPP over serial, the CubeNode ETH enables up to 12 Mbps bi-directional networking, facilitating transmission of MAVLink, CAN and other protocols—all through a single serial port without sacrificing additional telemetry or data interfaces. Ideal for UAV builds requiring robust, lightweight network integration.

Features

• High-Performance Dual-Core MCU
  Features Arm® Cortex®-M7 (480 MHz, double-precision FPU) paired with Cortex®-M4 (240 MHz, single-precision FPU), equipped with DSP instructions and MPU for secure, efficient processing.

• Lightweight, Compact Design
  Small PCB module (approx. 28 × 11 × 10 mm) weighing just ~2.7 g (7.3 g with cables).

• Robust Memory Profile
  Dual-bank 2 MB Flash and 1 MB RAM (192 KB TCM, 864 KB SRAM, 4 KB backup SRAM) enabling firmware upgrades and buffer handling.

• Ethernet via PPP Protocol
  Connects over one serial port (with flow control) to achieve network speeds up to 12 Mbps. Supports MAVLink, CAN, TCP/UDP traffic. Works out-of-box with CubeOrange+ and CubeRed on ArduPilot ≥ 4.5.
