Design and Options

Proper off the bat, the dimensions of the Speedybee F405 Wing MINI is its most hanging characteristic. This compact flight controller is considerably smaller than its sibling, the usual F405 Wing FC. Its small type issue is a big benefit for builds the place house is at a premium.

Regardless of its smaller measurement, it brings a number of notable options to the desk. The flexibility to change between C1 and C2 cameras is a contemporary addition not generally seen on F405 boards, enhancing versatility for pilots who make the most of a number of digicam setups.

One of many standout options is its wi-fi tuning functionality, proved to be helpful in organising and making parameter changes with out the effort of plugging within the USB cable.

The inclusion of SBUS enter pins and uncovered pins for UART1, permitting for compatibility with numerous radio programs like Frsky, ExpressLRS and Crossfire, is a considerate contact.

With 11 PWM outputs, six UARTs (one reserved for WiFi), and help for each digital and analog video transmitters, the F405 Wing Mini is designed to cater to a variety of flying kinds and preferences.

The equipment consists of each right-angle and vertical header pin choices for connecting servos and receiver, enhancing the flexibleness in mounting based mostly on the out there house inside your construct. The board additionally helps twin cameras and digital FPV programs, catering to a variety of person preferences.

Set up and Setup

The Speedybee F405 Wing Mini comes with the whole lot wanted for meeting, avoiding the widespread frustration of looking for suitable cables or connectors. The considerate inclusion of a capacitor and totally different boards for backside mounting choices speaks to Speedybee’s dedication to person comfort.

One factor to notice is the orientation of the ability distribution board, which is designed to take a seat on the high.

Organising the FC was a breeze, thanks partially to the detailed handbook and the SpeedyBee app’s intuitive interface. Whereas wi-fi firmware flashing just isn’t supported by the SpeedyBee app but, it does help INAV 7 from the get-go which is a significant plus. You too can flash firmware and configure the FC the standard approach utilizing your PC through USB cable.

The F405 Wing Mini’s small measurement didn’t compromise its functionality to ship a secure and responsive flight expertise. The board’s design facilitates straightforward wiring and element attachment, though the weird mounting gap sample might require some adaptation, akin to utilizing double-sided foam tape for set up.
