Request a component quote →What mounting pattern does the F405 controller use?+
The board uses the common 30.5 × 30.5 mm mounting pattern with M4 mounting holes.
Does it include a barometer and blackbox memory?+
Yes. The listed configuration includes an SPL06 barometer and 16 MB of onboard blackbox flash storage.
Can it be used in a high-voltage build?+
The supplier specification lists 3–8S input support. The ESC, motors, capacitor, wiring and every connected peripheral must also be rated for the selected battery voltage.
