The main control adopts F405 chip, 1MB FLASH, rich interfaces and complete functions Built-in TF card holder, barometer, gyroscope, OSD, reserved interface socket, which can be plugged in or soldered. PDB board with large current, built-in galvanometer detection. The default 5V BEC servo output is 8A. It can also be set to 6V/6.5 A and 7.4V/6A through the PDB jumper pad to power the servo The PDB is also integrated with 5VBEC to power the flight control and 9VBEC to power the image transmission (can be switched to 12V). There is also an additional 3.3VLD0 reserved There is an 5VBEC on the LED board that can be connected to four external WS2812 light strips. The control signal is provided by the LED Strip of F405. The extended USB interface board has a B00T button and a 110dBm buzzer with a switch that can turn it off Note: Since the 6P plug cable of the USB interface board and the 03 air end cable are both 6P, when connecting, be sure to check the cable type clearly and do not plug it in wrongly to avoid burning out the flight controller or O3. The 6P cable on the USB board is the green one CPU: STM32F405RG Sensor: -42688-P Firmware version: INAV JHEMCUF405WING.HEX Black box: Bring your own TF card Barometer: Support OSD: support IIC: support UART: 6 BEC: 5V/8A for servo (6V/6.5A, 7.4V/6A switchable), 5V/2.5A for flight control, 9V/2A for image transmission (12V/1.8A switchable) 3. 3V LD0 450MA Image transmission: supports analog image transmission, supports 03 and other high-definition air terminals Receiver: SBUS, IBUS, DSM2, DSMX, , ELRS CRSF, etc. Support WS2812 programmable LED Support buzzer Built-in voltage and current sensors (Due to different batches, the printed words on the product will be different, which does not affect use) Colour:Black Material:PCB Package Contents: 1 x Flight Controller Only the above package content, other products are not included.
