Design and Construct High quality
The SpeedyBee F405 AIO has a definite look, with giant purple heatsinks on each side of the board. These aren’t simply aesthetic—they enhance cooling and supply added bodily safety in crashes. The premium purple end makes the board stand out in comparison with the extra widespread black or inexperienced PCBs.
Regardless of its compact dimension of 33x33mm, the F405 AIO packs a punch. It’s sufficiently small for two″ builds, and it helps currents as much as 40A, making it additionally appropriate for as much as 5-inch builds, offered you’re not pushing the motors to their absolute limits. The flight controller has built-in 5V 2A BEC and a 9V 2A BEC, that are excellent for powering LEDs, VTXs, and cameras. Moreover, its 25.5×25.5mm mounting holes make it suitable with a variety of frames.
Weight and Dimension Concerns
Weighing 13.4 grams, the F405 AIO is barely heavier than different AIO boards with related specs, which often weigh round 9 grams. The extra weight comes primarily from the heatsinks, including round 3-4 grams. Whereas this gained’t impression cinewhoops or 5-inch FPV drones considerably, it may very well be a priority for ultra-light or sub-250g builds, the place each gram issues.
One other consideration is its thickness. At 8mm, it’s thicker than most AIO boards, which may have an effect on compatibility with compact frames. Be conscious of the FC peak when changing one other AIO flight controller, because it won’t match all builds.
Whereas the warmth sinks improve sturdiness and cooling, additionally they cowl many inside parts, making it more durable to establish sure pads. Fortunately, the included quick-start information is complete and extremely helpful. Preserve it useful for soldering or troubleshooting.
Key Options
ESC Amp Ranking
The SpeedyBee F405 AIO encompasses a 40A 4in1 ESC, greater than sufficient for the typical 5-inch or smaller builds. The ESC comes pre-flashed with BlueJay firmware, supporting DShot300 and DShot600 protocols, enabling easy motor efficiency and exact flight controls. Massive motor pads make soldering simple, even for freshmen.
4 UARTs
This flight controller presents 4 full UARTs for connecting peripherals equivalent to GPS, ExpressLRS/Crossfire receivers, VTX, and extra. There’s even an I2C connection, which is ideal for exterior compasses—best for iNav customers or these trying so as to add extra superior navigation options.
Built-in Bluetooth
Similar to SpeedyBee’s different flight controllers, Bluetooth is out there on this board. Paired with the SpeedyBee app, you possibly can wirelessly configure Betaflight settings, replace firmware, and even flash the board—no laptop computer required.
USB-C Extension
Some of the considerate options is the USB-C extension board. Whereas the FC has an onboard USB-C port, the breakout pads will let you join an exterior USB port and place it in a extra accessible location inside your body. That is notably useful for cinewhoops with enclosed frames.
Built-in Blackbox Logging
For these operating analog setups, the onboard OSD chip will show all of the important flight information proper in your goggles. The board additionally options 8MB of Blackbox storage, which is important for tuning your quad.
5V and 9V Twin BEC
The F405 AIO has twin BECs—a 5V 2A for powering your receiver and different 5V gadgets, and a 9V 2A particularly in your VTX. That is excellent for builds operating digital techniques just like the DJI O3 Air Unit, guaranteeing secure energy supply even beneath heavy hundreds.
Equipment
The LED Pad Breakout Board makes soldering a number of LED strips simpler by splitting the LED sign into 4 particular person pads.
If the onboard BEC’s aren’t sufficient, additionally they included an exterior BEC which presents 9V or 5V output for added energy.
Areas for Enchancment
Whereas the big purple warmth sinks enhance cooling and sturdiness, they’ve some downsides:
- Entry Points: The heatsinks partially cowl a number of pads and boot button, making troubleshooting and soldering tougher.
- Weight: The added weight (4–5 grams) may very well be a priority for ultra-light builds.
- Non-Detachable Design: The heatsinks are glued on, making them extraordinarily troublesome to take away.
Within the Speedybee Bee25 BNF Cinewhoop, they used this precise F405 AIO FC with out heatsinks. I want they supplied this heatsink-free model as properly for the weight-conscious builders. Or they might change the best way these heatsinks are mounted, as an example, as an alternative of glue they might simply use a few small screws.
Last Ideas
At simply $55, the SpeedyBee F405 AIO presents excellent worth, combining fashionable options with considerate design. Its Bluetooth integration, USB-C extension, and twin BECs make it one of the user-friendly AIO flight controllers obtainable immediately. The high-quality construct and premium look, coupled with wonderful efficiency, set it aside in its worth vary.
Whether or not you’re constructing a cinewhoop, a freestyle quad, or an iNav GPS drone, the SpeedyBee F405 AIO is a improbable alternative. It’s best for individuals who need a steadiness of efficiency, reliability, and ease of use.
