Holybro - Pixhawk Standard Baseboard V2B
by Holybro

The Holybro Pixhawk Standard Baseboard V2B is an upgraded, full-featured carrier interface engineered for modular autopilots adhering to the open-source Pixhawk Autopilot Bus (PAB) standard, including the Pixhawk 5X, Pixhawk 6X, and Pixhawk 6C (module version). Designed for commercial drones, industrial sUAS, and autonomous robotics platforms, the V2B baseboard provides a central connection hub for avionics, power distribution, and mission-critical communications.

Sharing identical electrical pinouts and functionality with the V2A variant, the V2B features a modified header pin orientation optimized for compact airframe layouts and streamlined cable routing. It breaks out dual-redundant power module inputs, 16 PWM outputs, 100Mbps high-speed Ethernet for companion computer integration, dual CAN buses, dual GPS ports, and four general-purpose telemetry ports utilizing secure, locking JST-GH connector interfaces.

Key Features

• Pixhawk Autopilot Bus (PAB) Standard: Fully compatible with Pixhawk 6X, Pixhawk 5X, Pixhawk 6C (module version), and modular flight controllers following the PAB interface standard.

• V2B Pin Header Orientation: Offers a specialized pin header layout designed to ease cable routing and connector strain in tightly packed drone frames.

• Dual Redundant Power Inputs: Features primary (Power1) and backup (Power2) power inputs with automatic power path switching and overvoltage protection.

• 100Mbps High-Speed Ethernet: Dedicated Ethernet interface enables high-bandwidth communication with companion computers (e.g., Raspberry Pi, NVIDIA Jetson).

• Comprehensive I/O Breakout: Provides 16 PWM servo outputs, dual CAN buses, 2x I2C ports, 1x SPI bus, and 4 telemetry/serial ports (Telem1–3, UART4).

• Locking JST-GH Connector Interface: Industrial-grade locking connectors prevent physical disconnections caused by high vibration and G-forces.
