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
