Product name:30.5X30.5mm Skystars F7 HD Pro4 MPU600 Flight Controller with 5V 10V BEC KM65 65A BL_32 128K F4 4in1 ESC Stack for RC FPV Racing Drone Precise details: What makes this FC PRO4 different from others? 1. Solder pads are the largest in size compared to other FC in market. 2. Proper solder pad spacing to avoid solder bridge and facilitate easy soldering. 3. ESC connector on top-side rather than bottom which makes it easy for repair. 4. TVS Diode for Reverse Polarity Protection and Voltage Spike Suppression. 5. Powerful 3A BEC to supply all your electronics. 6. Pads arrangement are executed in such a way that when you twist the wires of the camera VTX and RX you don't get any wire overlapping this gives you a uniform twist and clean look. 7. Support DJI O3 connector on the top side. 8. Support VTX ON/OFF Pit Switch. 9. Gyroscope independent power supply, No power lines near MPU6000 Gyro to avoid any EMI interference. 10. Two stages of Quality check to reduce any faulty electronic. 11. Comes ready with I2C support and INAV.
