Matek AP_Periph CAN Node CAN-G474

Unleash the Full Potential of Your Drone with the CAN-G474 Adapter Node

Introducing the CAN-G474, the ultimate adapter node for enthusiasts and professionals in the unmanned technology field. Embedded with the cutting-edge ArduPilot AP_Periph firmware, this board stands as a robust cornerstone in building or upgrading your drone’s functionality.

Technical Marvel for Enhanced Drone Operations

At the heart of CAN-G474 lies the powerful STM32G474CE microcontroller, equipped with 512KB of flash memory, ensuring swift and reliable processing capabilities. This adapter node isn’t just smart; it’s fast. With a CAN transceiver boasting data rates up to 5Mbit/s and the capability to support CANFD, high-speed communication within your UAV system is a breeze.

Versatile Connectivity for Comprehensive Control

Dive into a sea of connectivity options with the CAN-G474:

• Dual CAN Bus System: Manage complex setups with ease.
• Four UARTs & Two I2C Buses: Connect a wide array of peripherals including GNSS, rangefinders, and more.
• Single SPI Interface: Designed specifically for peripherals like the RM3100, with dedicated SPI pads located on the underside for a clean, efficient setup.
• Eleven PWM Outputs: Whether it’s servos or ESCs, all PWMs support DMA/DShot for precision control.

Optimized for ArduPilot Software

Leverage the ArduPilot driver library seamlessly. The CAN-G474 transforms supported peripherals — from GNSS and compasses to electronic fuel injectors — into DroneCAN bus peripherals. This makes integrating multiple devices into your drone ecosystem as simple as plug-and-play.

Built Tough for Unrelenting Performance

Designed to perform in the most demanding environments, the CAN-G474 operates within a temperature range of -30 to 85 °C. It’s not just tough, it’s compact and lightweight too, making it an ideal choice for any drone build.
