JIYI CAN HUB - Professional CAN Bus Splitter and Power Expansion Module for Drone Flight Controllers

The JIYI CAN HUB (specifically the CAN HUB-12 architecture) serves as the centralized digital nervous system for commercial multirotors, optimizing complex payload data flow.

Massive Peripheral Network Expansion :

Complex agricultural and industrial mapping drones use numerous external telemetry sensors. Instead of daisy-chaining components—which can introduce critical points of hardware failure—this heavy-duty CAN bus hub acts as a robust network splitter, allowing multiple CAN-based modules to transmit data simultaneously back to the primary autopilot with ultra-low latency.

Integrated 6S to 14S High-Voltage BEC :

Say goodbye to external voltage regulators and complex distribution wiring. This intelligent device features a built-in step-down step-down power converter that handles high-voltage inputs up to 14S LiPo. It steps this down internally to provide a continuous, ultra-stable 12V output, shielding sensitive radar electronics from hazardous electrical flight motor sag.

Clean Signal Routing Architecture :

By localizing your communication ports onto a single distribution block, the module drastically lowers electromagnetic interference (EMI) across your airframe. This helps you build neat, standardized avionics trays where wiring footprints are minimized and field tracing is streamlined.

• JIYI K++, K++ V2, K3A Pro, and KX agricultural flight systems

Frequently Asked Questions :

Q1: Why is a CAN Hub required when building an agricultural spraying drone?

Ans: Advanced setups require multiple external systems—like terrain-following radar, obstacle avoidance sensors, RTK antennas, and flow meters. Because your flight controller has limited native CAN ports, this hub expands that single port safely to prevent bus overloading.

Q2: What is the purpose of the built-in XT30 connector on the JIYI CAN Hub?

Ans: The integrated XT30 connector taps directly into the internal step-down circuit to deliver clean, dedicated 12V power. This allows operators to run high-draw external peripherals directly from the hub without putting extra electrical strain on the flight controller.

Q3: Can I power this CAN hub directly from a 12S drone battery pack?

Ans: Yes, absolutely. The internal power management system is fully optimized to handle massive incoming voltages ranging from 6S all the way up to 14S LiPo configurations safely, eliminating the need for a secondary power distribution board link.

Q4: How does using a CAN bus network improve flight safety over older protocols?

Ans: The CAN bus protocol features extreme resistance against intense electrical noise generated by high-power ESCs and motors. It allows multiple sensors to share communication lines reliably, ensuring critical obstacle data reaches the autopilot instantly.
