K3-A Pro Flight Controller Kit: Genuine JIYI Hardware for Ag UAVs

This is a genuine JIYI K3-A Pro kit — the flight-controller module is clearly stamped “K3-A PRO FLIGHT CONTROLLER” with JIYI’s own branding, and the labeled port layout (motor outputs M1-M8, RTK and EXT expansion, POW/GPS/LFS/PUMP link ports, and CH2-CH6/RC indicator ports) matches JIYI’s own documentation exactly. It’s the upgraded successor to the original K3-A, a flight controller JIYI states was used by roughly 70% of domestic plant-protection drone manufacturers through 2017-2018 — a track record that carries into this Pro revision.

The core upgrade is a dual-GNSS magnetic-compass configuration for redundant heading and positioning, paired with agricultural-specific software: polygon-route planning for irregular field boundaries, AB-point straight-line spraying, breakpoint continuous spray (resuming exactly where it left off after a refill stop), and compatibility with flow-sensor modules for real-time pesticide-flow monitoring. One important clarification: this runs JIYI’s own proprietary flight-control firmware and configuration app — it is not a PX4 or ArduPilot board, so it won’t work with Mission Planner, QGroundControl, or other open-source ground-control software.

Frequently Asked Questions

Does the K3-A Pro Flight Controller Kit run PX4 or ArduPilot?
No — this is a genuine JIYI K3-A Pro, which runs JIYI’s own proprietary flight-control firmware and configuration app. It won’t work with Mission Planner, QGroundControl, or other open-source ground-control software.
What’s included in the kit?
The flight-controller module, a GPS/GNSS module, an LED indicator module, a PMU power-management unit, and the connecting cables needed to start a spraying-drone build.
How is this different from JIYI’s original K3-A?
The Pro revision adds a dual-GNSS magnetic-compass configuration for redundant heading and positioning, on top of the same agricultural-focused feature set that made the original K3-A a widely-used flight controller among plant-protection drone manufacturers.
Can it handle irregularly-shaped fields?
Yes — polygon-route planning lets it map non-rectangular field boundaries, alongside AB-point straight-line spraying for simpler rectangular passes.
What batteries and frames does it support?
2S to 12S LiPo batteries, and quadcopter, hexacopter, or octocopter frames in +, X, V, or coaxial configurations.
What’s the operating temperature range?
0°C to 60°C during operation, with a storage range of -40°C to 60°C.
