Product overview
The CUAV V5 nano flight controller provides the electrical integration point between vehicle power, motor or servo control, navigation peripherals and communication equipment. Its interface architecture includes separate M1~M8 and A1~A8 PWM output groups, I2C connections for devices such as an external compass, and CAN connections for UAVCAN peripherals. USB Type-C supports computer communication and firmware loading, while DSU7 exposes FMU debug information.
The kit configuration described includes an HV_PM power module supporting 2~10s LiPo batteries, an SBUS cable and a factory-installed SD card. Integration planning must accommodate the controller’s mounting orientation and a GPS/compass location away from other electronics. The recommended NEO v2 GPS combines navigation and safety-related peripherals, but its inclusion is not established. Procurement checks should address firmware-dependent PM2 support, compatible RC equipment for manual control, and safety-switch or external-buzzer requirements when the recommended GPS arrangement is not used.
Specifications
| Specification | Value & conditions |
|---|---|
| Product type and purpose | CUAV V5 nano flight controller for integration with vehicle power and peripherals. |
| POWER1 | Power-module connection for power input and AD voltage and current detection. |
| PM2 firmware limitation | PM2 support depends on firmware.Do not use PM2 with PX4; ArduPilot firmware can support it. |
| TF CARD | SD-card interface for log storage. |
| M1~M8 | PWM outputs for controlling motors or servos. |
| A1~A8 | PWM outputs for controlling motors or servos. |
| DSU7 | FMU debugging and reading debug information. |
| I2C2/I2c3/I2c4 | Connections for I2C devices, including an external compass. |
| CAN1/CAN2 | Connections for UAVCAN devices, including CAN GPS. |
| TYPE-C(USB) | Computer communication connection, including firmware loading. |
| GPS&SAFETY | Neo GPS connection incorporating GPS, safety-switch and buzzer interfaces. |
| TELEM1/TELEM2 | Telemetry-system connections. |
| DSM/SBUS/RSSI | DSM satellite-receiver input, SBUS remote-control receiver input and RSSI signal-strength return-module input.Select and bind a compatible transmitter and receiver for manual control. |
| Included power module and battery support | HV_PM included; supports 2~10s LiPo batteries.The stated battery support applies to the included HV_PM power module. |
| Power-module wiring | 6-pin power-module connector connects to POWER1.The wiring instruction names HW_PM, while the preceding kit description names HV_PM; confirm the supplied module. |
| Included receiver cable | SBUS cable supplied in the kit. |
| Factory-installed SD card | SD card installed at the factory.The factory has already inserted the card. |
| Controller mounting | Alternative mounting orientations require corresponding software configuration.Configure controller software to match the actual mounting orientation when the recommended/default orientation cannot be used. |
| Recommended GPS module | NEO v2 GPS with GPS, compass, safety switch, buzzer and LED status light.Recommended peripheral. |
| GPS/compass installation | Frame-mounted GPS/compass module with forward-facing direction marker.Position the GPS/compass module away from other electronics and align its direction marker with the vehicle front. |
| CAN GPS wiring | Connect CAN GPS to the controller CAN interface.Applies when using CAN GPS. |
| Safety-switch requirement without GPS | Attach a safety switch directly to GPS1 when operating without GPS.Required when flying without GPS to permit arming and flight. |
| Buzzer limitation | Buzzer operation may require an external buzzer with alternative GPS configurations.Applies when the recommended GPS is not used; an external buzzer may be needed. |
| Radio-control requirement | Manual control requires an RC radio system.RC is required for manual control; PX4 autonomous flight modes do not require a radio system. |
| Optional telemetry installation | Connect the vehicle telemetry radio to TELEM1/TELEM2.Telemetry is optional; connection to TELEM1/TELEM2 needs no further configuration. |
| Motor and servo wiring | Motors and servos connect to the ports identified as MAIN and CAP.Follow the connection order specified for the selected vehicle in the Airframe Reference. |
