Overview: The main control uses F405 chip, 1MB FLASH, rich interface, full-featured. Built-in TF card holder, barometer, gyroscope, OSD, reserved interface socket, can be inserted or welded. With high current PDB board, built-in ammeter detection. Default 5V BEC servo output 8A, can also be set to 6V/6.5A and 7.4V/6A servo power supply through the jumper pads of the PDB. 5V BEC is also integrated on the PDB to power the flight controller and 9V BEC to power the mapping (can be switched to 12V). There is an additional 3.3V LDO reserved. There is a separate 5V BEC on the LED board that can be connected to four WS2812 strips, and the control signal is provided by the LED Strip on the F405. The extended USB interface board has a BOOT button, and a 110 dBm buzzer with a switch to turn it off. Note: Since the 6P plug line of the USB interface board and the line of the DJI O3 sky end are both 6P, when connecting, be sure to look at the type of line, don't plug in the wrong way to avoid burning the flight control or DJI O3. the 6P line of the USB board is the one with the green color in it.
