Description: 【Rational Layout Designed】The board is designed with a rational layout and larger solder pads. It is very easy for pilots to solder external electronics. Soldering motor wires to pad directly allows lower resistance for more current on motors. Besides, solder pads are reinforced by thick copper and edge plating process, ensuring a and durable use. 【F411 Chip】The flight controller has been updated to F411, can totally handle 45A continuous current, gives pilots a powerful flight. 【Pluggable Connector】 F411 AIO 45A flight controller integrated digital VTX connector and receiver connector, just plug and play, which is convenient for installation 【Compatible Motors】F411 AIO 45A FC is for 110X/120X/140X series motors, pilots can build a bigger quad with this powerful FC to save weight 【Suitable Drones】Comes with a 26mm x 26mm whoop mounting pattern, this board can be added to both the toothpick drone and the cinematic whoop quadcopter.
