The CUAV Nora+ Flight Controller is a high-performance autopilot built on the STM32H743 processor with a Cortex-M7 core, running at up to 480MHz. With advanced industrial-grade IMUs, an ultra-low drift temperature compensation system, and full compatibility with ArduPilot firmware, it delivers precise, stable, and efficient control for academic research, commercial UAVs, and professional integration projects.
The SIYI UniRC 7 Remote Controller is a versatile handheld ground station featuring a dual-band 2.4/5 GHz transmission system with up to 40 km range and real-time 4K30 video decoding. Its 7-inch 1080p display, ultra-low latency, and intelligent channel switching ensure clear visuals and reliable operation in demanding environments.
In this Nora+ and Rc7 connecting tutorial, we demonstrate how to connect the CUAV Nora+ Flight Controller with the SIYI UniRC 7 Remote Controller, covering cable connections, port configurations, and software setup to ensure a stable link between flight control and ground station.
Wiring Instructions
The cables used are: Nora+ power module, RC7 receiver power cable, RC7 S. bus cable, RC7 telemetry cable, JST to XT60 adapter. The S.Bus port on the RC7 uses a GH1.25 2-pin connector, while the RC port on the Nora+ uses a 2.54mm 3-pin Dupont connector.
- Connect the UART1 port (GH1.25 3-pin) on the RC7 receiver to the TELEM1 port (6-pin) on the Nora+.
- Connect the Power C port on the Nora+ to the power module.
- Connect one end of the power module to the battery, and the other end to the adapter.
- Power the RC7 receiver using its XT30 connector on one end and JST2.54 connector on the other.
Ground Station Setup
Power on the RC7 remote controller and open QGroundControl (QGC).
- Navigate to Application Settings → Communication Links and click Add.
- Name the link, set Type to UDP, Port to 0, and Address to
192.168.144.20:19856. - Click Add Address, then OK.
- Return to the Communication Links page, select the link, and click Connect.
- In the flight interface, confirm that the flight controller is connected to the ground station.
Radio and Data Link Configuration
- In QGC, go to Settings → Radio and move the joysticks to verify S.Bus connection.
- Open UniGCS, access Remote Controller Settings → Data Connection.
- Set Datalink1 to UDP, Baud Rate1 to 57600.
- In the Flight Controller interface, set Connection Type to UDPCl and Address to
192.168.144.20:19856.
Flight Interface and Control
Return to the main screen of UniGCS. The center black disc shows the real-time status of the flight controller. The top-left corner provides one-click takeoff and one-click landing functions, ensuring quick and efficient operation.
