Technical Highlights

STM32F405 Flight Controller

The SpeedyBee F405 V4 flight controller combines an STM32F405 MCU with an ICM42688P gyroscope, DPS310 barometer and AT7456E analog OSD for FPV racing, freestyle and multirotor applications.

Bluetooth Configuration

Built-in Bluetooth connectivity supports wireless flight-controller configuration through the SpeedyBee App, allowing convenient parameter adjustment without connecting the FC directly to a computer.

MicroSD Blackbox Logging

The onboard microSD card slot provides removable Blackbox storage for flight-log recording and tuning analysis. Compatible SDSC or SDHC cards must use FAT16 or FAT32 formatting.

BLS 60A 4-in-1 ESC

The included 3–6S BLHeli_S ESC delivers 60A continuous current per channel and supports DShot300 and DShot600. A heat sink, TVS protection and external low-ESR capacitor help manage electrical and thermal stress.

Eight Motor Outputs

The flight controller provides eight motor outputs for layouts such as X8 and Y6. The supplied BLS 60A unit is a four-channel ESC, so eight-motor installations require additional compatible ESC channels.

Compatibility and Installation Notes

Use the SPEEDYBEEF405V4 Betaflight target and V4-specific wiring documentation.
Do not flash SpeedyBee F405 V5 firmware onto this V4 flight controller.
The included BLS 60A ESC is intended for 3–6S LiPo power systems.
Observe correct polarity when installing the external low-ESR capacitor.
Confirm motor, receiver, GPS, video-system and peripheral wiring before applying battery power.
Eight-motor configurations require additional compatible ESC channels because the supplied ESC provides four motor channels.
Actual motor and propeller compatibility depends on the complete propulsion system and operating load.

FAQ

Is this the SpeedyBee F405 V4 or F405 V5 stack?

This product is the SpeedyBee F405 V4 stack with the BLS 60A BLHeli_S 4-in-1 ESC. It is not the F405 V5 OX32 55A stack.

Which Betaflight target should be used?

Use the SPEEDYBEEF405V4 target. Do not install firmware intended for the SpeedyBee F405 V5.

What battery voltage does the stack support?

The BLS 60A ESC and flight-controller stack support 3–6S LiPo power systems.

What is the current rating of the ESC?

The BLS 60A 4-in-1 ESC is rated for 60A continuous current per channel and 80A burst current per channel for up to 10 seconds.

Does the flight controller support Bluetooth configuration?

Yes. Built-in Bluetooth supports compatible wireless configuration through the SpeedyBee App.

Does the FC have Blackbox storage?

Yes. It uses a removable microSD card for Blackbox logging. Use a compatible SDSC or SDHC card formatted as FAT16 or FAT32.

Can this stack control eight motors?

The flight controller has eight motor outputs and can support configurations such as X8 or Y6. However, the included ESC provides four motor channels, so additional compatible ESC channels are required.

Does the BLS 60A ESC support ESC telemetry?

No. The ESC provides current sensing but does not support ESC telemetry.

B2B Procurement FAQ

What exact model should be stated on a purchase order?

Specify SpeedyBee F405 V4 BLS 60A 30x30 FC and ESC Stack. The manufacturer SKU is SB-F4V4-60-STACK.

How can buyers avoid receiving the F405 V5 version?

State F405 V4, BLS 60A, BLHeli_S and firmware target SPEEDYBEEF405V4 on the purchase order. Do not use F405 V5, OX32 55A or V5 firmware descriptions for this item.

Is the SpeedyBee F405 V4 stack still available?

The manufacturer currently identifies this model as discontinued. Buyers should confirm available stock, product condition and quantity before placing an order.

What should be checked during incoming inspection?

Verify the F405 V4 board revision, BLS 60A ESC identification, 30.5 × 30.5 mm mounting pattern, supplied components and physical condition before assembly.

Should firmware be updated before delivery?

Firmware requirements should be confirmed for each order. Any update must use the SPEEDYBEEF405V4 target and should be tested before shipment.

Are MOQ, lead time and packaging fixed?

MOQ, lead time, available quantity and packaging depend on current inventory and order requirements. Confirm these commercial details before purchase.
