FC & ESC Connection
Use the 8-pin cable in the package to connect the FC and the ESC. Or solder 8 wires directly to the 8 pads on each end.
Method 1 – Using 8-pin cable
Use any end of the 8-pin JST cable to connect the FC to the ESC.
Method 2 – Direct soldering
Solder 8 wires to the 8 pads on each end referring to the pad definition below.

LED Indicator Definition
RED LED – Power Indicator.Solid Red after powering up.
GREEN LED – Bluetooth status light. Solid Green indicates Bluetooth is connected.
BLUE LED – Flight controller status light which is controlled by the flight controller firmware.
Orange LED – LED Control Mode Indicator. It indicates the 4 sets of LED strips connected to LED1-LED4 pads on the corners of the flight controller are controlled by Betaflight
firmware(BF_LED mode) or the Bluetooth chip(SB_LED mode).
Solid Orange ：tindicates the 4 x LEDs are in SB_LED mode. In this mode, when the FC is powered on and in standby mode, press the BOOT button to cycle the display modes of the LEDs. You could also change modes in the app wirelessly.
OFF ：indicates the 4 x LEDs are controlled by Betaflight firmware.
Long press the button for 3 seconds to switch the control modes between BF_LED mode and SB_LED mode.
[A] Only if the flight controller gets bricked and can’t power up, please follow these steps to re-flash firmware for it:
- Insert a USB A to TYPE-C cable to your PC.
- Press and hold the BOOT button, insert the USB cable into the flight controller, then release the BOOT button.
- Open Betaflight/Emuflight/INAV configurator on the PC, go to the ‘Firmware Flashing’ page, choose the target ‘SPEEDYBEEF405V3’ and flash.
[B]. When the FC is powered on and in standby mode, the BOOT button can be used to controller the LED strips connected to LED1-LED4 pads on the corners. 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 the Betaflight firmware.

FC Configuration
FC Firmware Update
SpeedyBee F405 V3 flight controller does not support wireless firmware flashing,
so please flash firmware for it on your PC following the steps below:
- Connect the flight controller to the PC with a USB cable
- Open Betafight/Emuflight/INAV configurator on your PC. Take Betaflight configurator as an example, go to the ‘Firmware Flashing’ page, choose the target ‘SPEEDYBEEF405V3’ and flash.

Layout
Connection with Motors & Power Cable
Note: In order to prevent the stack from being burnt out by voltage spikes
on powering up, it is strongly recommended to use the Low ESR capacitor in the package.
ESC Configuration
- If you’d like to use a PC configurator, we recommend the ESC Configurator.
ESC Firmware Update
- You could flash both BLHeli_S and Blue Jay firmware for this ESC.
You need to pulg in the battery to the F405 V3 and then connect a USB
cable between the F405 V3 and your PC. Then flash ESC firmware
(BLHeli_S or Blue Jay) in the following online configurator:
