ReadytoSky I2C Splitter Hub with Cable – Essential Pixhawk/APM Expansion
Maximize the peripheral capacity of your flight stack with the ReadytoSky I2C Splitter Hub. Standard flight controllers like the Pixhawk or APM often come with a limited number of I2C ports, which can become a bottleneck when adding advanced sensors. This bus expansion module acts as a high-speed "power strip" for your data, allowing you to connect up to four additional I2C devices—such as external compasses, digital airspeed sensors, LED modules, or specialized laser rangefinders—using only a single port on your flight controller.
Crafted for reliability in high-vibration environments, the ReadytoSky splitter ensures stable data transmission across all connected nodes, making it a critical component for professional UAV builds and complex autonomous platforms.
Key Highlights:
4-Way Port Expansion: Instantly converts one I2C port into four, enabling the simultaneous use of multiple external sensors and accessories.
Seamless Compatibility: Designed specifically for the Pixhawk (2.4.6/2.4.8) and APM 2.8 ecosystems, utilizing standard 4-pin JST-GH or DF13 style connections.
Plug-and-Play Installation: Includes a pre-terminated 4-wire cable, allowing for immediate integration without the need for custom soldering or wiring harnesses.
Ultralight & Compact: Measuring just 37mm x 18.3mm, this hub fits easily into tight frames and adds negligible weight to your aircraft's takeoff profile.
Robust Data Bus: Features a high-quality PCB that maintains signal integrity across all four ports, preventing sensor dropouts during critical flight maneuvers.

Pro-Builder Tip:
When connecting multiple high-draw I2C peripherals (like high-brightness RGB LED boards), ensure your Flight Controller’s internal regulator can handle the cumulative current. For complex setups with an airspeed sensor and external GPS/Compass, the ReadytoSky Splitter is the cleanest way to keep your wiring loom organized and "pro-tier" in appearance!
