SpeedyBee F745 35A BLS claims to be the world’s first AIO flight controller with built-in wireless connectivity (Bluetooth and WiFi). It allows changing everything right on the flight field using your mobile phone. You can configure a new radio receiver, motor layout, PIDs, and other things.
The flight controller measures 36.5×36.5×7 and it has a 25.5×25.5 mounting pattern. Weighting just 10 grams it is perfect to build FPV drones that weigh less than 250 grams. It supports PPM, Crossfire, and ELRS radio receivers. Thanks to the 4 UART ports it can be equipped with GPS and other types of sensors. Another great feature is the onboard DJI Air Unit plug.
The integrated 35A ESC has powerful and durable Toshiba MOSFETs and supports full BLHeli_S configuration.
