F405 V3 FC

● BOOT Button: Supported.

[A]. Press and hold BOOT button and power the FC on at the same time will force the FC to enter DFU mode, this is for firmware flashing when the FC gets bricked.

[B]. When the FC is powered on and in standby mode, the BOOT button can be used to control the LED strips connected to LED1-LED4 connectors on the bottom side. By default, short-press the BOOT button to cycle the LED displaying mode. Long-press the BOOT button to switch between SpeedyBee-LED mode and BF-LED mode. Under BF-LED mode, all the LED1-LED4 strips will be controlled by Betaflight firmware.

● Blackbox MicroSD Card Slot: *Betaflight firmware requires the type of the microSD card to be either Standard (SDSC) or High Capacity (SDHC), so extended capacity cards (SDXC) are not supported(Many high-speed U3 cards are SDXC). Also, the card MUST be formatted with the FAT16 or FAT32 (recommended) filesystems. So, you could use any SD card less than 32GB, but Betaflight can only recognize 4GB maximum. We suggest you use this 3rd party formatting tool and choose 'Overwrite format' and then format your card. Also, check out here for the recommended SD cards or buy the tested cards from our store.

● 5V Output: 9 groups of 5V output, four +5V pads and 1 BZ+ pad( used for Buzzer) on the front side, and 4x LED 5V pads. The total current load is 2A.

● Traditional Betaflight LED Pad: Supported. 5V, G, and LED pads on the bottom of the front side. Used for WS2812 LED controlled by Betaflight firmware.

● 9V Output: 2 groups of 9V output, one +9V pad on the front side and the other included in a connector on the bottom side. The total current load is 2A.

● 4.5V Output: Supported. Designed for the receiver and GPS module even when the FC is powered through the USB port. Up to 1A current load.

Power Input: 3S - 6S Lipo(Through G, BAT pins/pads from the 8-pin connector or 8-pads on the bottom side)

Current Sensor Input: Supported. For SpeedyBee BLS 50A ESC, please set scale = 386 and Offset = 0.

● 3.3V Output: Supported. Designed for 3.3V-input receivers. Up to 500mA current load.

● DJI Air Unit Connection Way: Two ways supported: 6-pin connector or direct soldering.

● I2C: Supported. SDA & SCL pads on the front side. Used for magnetometer, sonar, etc.

● Supported Flight Controller Firmware: BetaFlight(Default), EMUFlight, INAV

● UART: 5 sets(UART1, UART2, UART3, UART4(For ESC Telemetry), UART6)

● BLE Bluetooth: Supported. Used for Flight Controller configuration

● SmartPort: Use any TX pad of UART for the SmartPort feature.

● ESC Signal: M1 - M4 on the bottom side and M5-M8 on the front side.

● BetaFlight Camera Control Pad: Yes(CC pad on the front side)

● RSSI Input: Supported. Named as RS on the front side.

● Mounting: 30.5 x 30.5mm( 4mm hole diameter)
