Stack consisting of SucceX-E F722 V1.4 control unit and SucceX-E 45A V2 controller suitable for freestyle and racing copters. The control unit uses a modern F722 processor and has 16MB of memory for a black box. Nice are the connectors on the bottom of the board, which minimize the need for soldering and thus facilitate construction. The 45A load controller can be used with all common motors used on 5" drones. The solder pads are located at the corners, so there is good access to them even if there is a control unit above the controller.
