AeroBridge

 

AeroBridge – Universal DroneCAN Conversion Module

Overview

AeroBridge is a compact and lightweight interface module that converts traditional peripheral interfaces (PWM, UART, I²C, SPI, GPIO, ADC) into DroneCAN-compatible nodes. Powered by open-source PX4 DroneCAN and ArduPilot AP_Periph firmware, AeroBridge brings modern CAN-based communication to legacy UAV components, enhancing system reliability, modularity, and performance.

 

Key Features:

• Converts PWM / UART / I²C / SPI / GPIO / ADC to DroneCAN

• Fully compatible with ArduPilot AP_Periph and PX4 DroneCAN

• One-cable CAN communication for reduced wiring

• Noise-resistant, fault-tolerant data transfer

• Firmware-configurable peripheral modes and node settings

• Ideal for servos, ESCs, GPS modules, IMUs, telemetry, and other UAV devices

• Plug-and-play architecture with DroneCAN dynamic node ID allocation
