Smachd-itealaich SpeedyBee F405 V5 aig a’ mhullach View — Barr view of the SpeedyBee F405 V5 Flight Controller.

SpeedyBee F405 V5 Flight Controller Layout — Detailed layout of the F405 V5 Flight Controller, showing component labels and connections.

The F405 V5 Flight Controller features an STM32F405 MCU and an ICM42688P Gyro for precise flight control. It includes a built-in barometer (SPA06-003) for accurate altitude readings and an AT7456E OSD chip for on-screen display. Connectivity includes a new Type-C USB port and full-featured Bluetooth tuning via the SpeedyBee App, allowing for wireless firmware flashing and parameter tuning. It supports 6-pin direct plug-in or solder connection for DJI Air Units and has a built-in 16MB Blackbox storage chip for flight data logging.

Power outputs include 9 groups of 5V output (total 1.5A), 2 groups of 9V output (total 3A) with PINIO remote on/off control, 1 group of 3.3V output, and 3 groups of 4.5V output (max 1A) for peripherals like receivers and GPS modules. It supports 8 motor outputs (M1-M4 on bottom, M5-M8 on front) and multiple UARTs for various peripherals.

SpeedyBee BLS 55A 4-in-1 ESC

The BLS 55A 4-in-1 ESC is designed for 3-6S LiPo input, providing a continuous current of 55A per channel (220A total) and a burst current of 70A (280A total) for 10 seconds. It features a built-in TVS protective diode for surge protection and includes a 1000uF Low ESR Capacitor in the package for enhanced stability. The ESC supports DSHOT300/600 protocols and current sensing (Scale=400, Offset=0). It also supports ESC Telemetry.

ESC Protection Features — The ESC includes a TVS Protective Diode, 21 onboard TDK capacitors, and supports an external 1000uF high-capacity electrolytic capacitor for upgraded protection against voltage spikes and interference.

5. Stàladh

A' cur suas

The SpeedyBee F405 V5 FC and BLS 55A ESC both feature 30.5 x 30.5mm mounting holes with a 4mm hole diameter. They are designed to be stacked together using the provided silicone grommets and screws.

FC and ESC Installation Methods — Diagram illustrating soldering, direct plug, standard, and reverse installation methods for the FC and ESC. When fixing the stack, use M3 black silicone washers to ensure sufficient space between the flight controller and the ESC.

Connecting the FC and ESC

The FC and ESC can be connected via a 10-pin connector or by direct soldering. The 10-pin design provides enhanced safety redundancy.

FC and ESC Connection with Motors — Connection diagram for the FC and ESC with motors, including the 1000uF Solid Capacitor and XT60 Power Cable. It is strongly recommended to use the included 1000uF solid capacitor to protect the AIO flight controller from instantaneous voltagspìcean nuair a thèid a chumhachdachadh air.

DJI Air Unit Connection Diagrams — Diagrams for connecting the FC to DJI O3 Air Unit, RunCam Link/Caddx Vista Air Unit, and DJI Air Unit V1 using the 6-pin cable.

Receiver Specific Notices

SBUS Receiver Importance Notice — Importance notice for SBUS receiver: When using an SBUS receiver, the SBUS signal wire must be connected to the SBUS pad on the front side of the flight controller (this pad internally uses UART2). If also using a DJI Air Unit (O3/Link/Vista/Air Unit V1), you must disconnect the SBUS signal wire from the Air Unit harness. Failure to do so will prevent the SBUS receiver from being properly recognized by the flight controller. Use tweezers to pick out the SBUS wire from the 6-pin harness connector (or directly cut this wire) and insulate the exposed part of the wire carefully.

ELRS Receiver Importance Notice — Importance notice for ELRS receiver: We recommend connecting the ELRS receiver's TX and RX to the T2 and R2 pads on the flight controller. However, when using the DJI Air Unit simultaneously, some ELRS receivers may not be recognized properly by the flight controller. If you encounter this issue, you need to disconnect the SBUS signal wire from the Air Unit harness. You can use tweezers to pick out the SBUS wire from the 6-pin harness connector (or directly cut this wire) and insulate the exposed part of the wire carefully.

7. Rèiteachadh

Tiùladh gun uèir tro aplacaid SpeedyBee

Configure FC and ESC via Bluetooth — The SpeedyBee app allows you to configure your FC and ESC via Bluetooth, enabling wireless tuning and firmware updates.

The SpeedyBee F405 V5 FC supports full-featured Bluetooth tuning. Connect to the SpeedyBee App on your smartphone to flash FC firmware, tune parameters, and configure your quad anytime, anywhere. Ensure MSP is enabled with Baud rate 115200 on UART4 for Bluetooth connection.

Atharrachadh Stiùireadh Motair

You can change motor directions wirelessly using the SpeedyBee app. Connect to the app, navigate to 'Motors' and then 'Motor Direction Settings' to adjust as needed.

Smachd stiall LED

LED Pads with Simple Switching — Diagram showing the FC with four sets of LED pads, allowing for simple switching of LED presets. LED strips could be purchased separately. Long press the boot button to switch to Betaflight LED mode.

The FC supports 4 sets of LED pads. When the FC is powered on and in standby mode, the BOOT button can be used to control the LED strips connected to LED1-LED4 connectors on the bottom side. Short-press the BOOT button to cycle through different LED displaying modes. Long-press the BOOT button to switch between SpeedyBee-LED mode and BF-LED mode. In BF-LED mode, all LED1-LED4 strips will be controlled by Betaflight firmware.

8. Stiùireadh Obrachaidh

Once installed and configured, your SpeedyBee F405 V5 Stack is ready for flight. Ensure your radio transmitter is properly bound and configured with your receiver. Always perform pre-flight checks, including propeller security, battery level, and control surface response, before each flight.

Cumhachd air: Connect your LiPo battery to the XT60 connector. The FC and ESC will initialize.
Armachd: Arm your drone using your configured arming switch on your radio transmitter.
Itealaich: Operate your drone according to standard FPV flight practices.
A' dì-armachadh: Disarm your drone using your configured disarming switch after landing.

9. A ’dèanamh trioblaid

Flight Controller Not Responding / Bricked

If your FC becomes unresponsive or appears 'bricked', you can force it into DFU (Device Firmware Upgrade) mode for firmware flashing:

Press and hold the BOOT button on the FC.
While holding the BOOT button, connect the FC to your computer via the USB Type-C cable.
The FC should now be in DFU mode, allowing you to flash new firmware using Betaflight Configurator.

SD Card Compatibility Issues

SD Card Compatibility Information — Information regarding SD card compatibility for the F405 V5 Flight Controller. The F405 V5 FC supports Standard (SDSC) or High Capacity (SDHC) microSD cards under 32GB. Extended capacity cards (SDXC) are not supported. Cards must be formatted with FAT16 or FAT32. Betaflight can only recognize a maximum of 4GB.

Betaflight firmware requires the microSD card to be either Standard (SDSC) or High Capacity (SDHC) and under 32GB. Extended Capacity cards (SDXC) are not supported. The microSD card MUST be formatted with the FAT16 or FAT32 (recommended) format. While you can use any SD card less than 32GB, Betaflight can only recognize a maximum of 4GB. It is recommended to use a 3rd party formatting tool and choose 'Overwrite format' when formatting your card.
