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: indicates the 4x 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.
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.

BOOT Button

1. Only if the flight controller gets bricked and can't power up, please follow these steps to re-flash firmware for it:
   1. Insert a USB A to TYPE-C cable to your PC.
   2. Press and hold the BOOT button, insert the USB cable into the flight controller, then release the BOOT button.
   3. Open Betaflight/lNAV configurator on the PC, go to the Firmware Flashing page, choose the target 'SPEEDYBEEF405V4' and flash
2. When the FC is powered on and in standby mode, the BOOT button can be used to control the LED strips connected to LED 1 -LED4 pads on the corners. 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. The default mode is BF-LED mode.

FC's Peripheral Connection

Note 1: 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.
Note 2: The FC and ESC can also connected via direct soldering. Soldering pads definition is as follows.

Cable Connection vs DJI 03 Air Unit

Use 6-pin cable comes with the 03 Air Unit.

Cable Connection vs RunCam Link/ Caddx Vista Air Unit

Use 6-pin cable comes with the F405 V4 stack.
(See the accessory No. 11 in the package section)

Cable Connection vs DJI Air Unit V1

Use 6-pin cable comes with the F405 V4 stack.
(See the accessory No. 11 in the package section)

Importance notice for SBUS receiver

V\/hen using an SBUS receiver, the SBC-JS signal of the receiver must be connected to the SBUS pad on the front side of the flight controller (this pad internally uses OART 2).

If you are also using the DJI Air Unit(03/Link/Vista/Air Unit VI), you will need to disconnect the SBUS signal wire from the Air Unit harness. Failure to do so will prevent the SBUS receiver from being properly recognized by the flight controller. You can use tweezers to pick out the SBUS wire from the 6-pin harness connector (or directly cut this wire) and insulate the exposed part of the wire carefully.

Importance notice for ELRS receiver

We recommend connecting the ELRS receiver's TX and RX to the T2 and R2 pads on the flight controller. However, when using the DJI Air Unit simultaneously, some ELRS receivers may not be recognized properly by the flight controller. If you encounter this issue, you need to disconnect the SBC-JS signal from the Air Unit harness. You can use tweezers to pick out the SBUS wire from the 6-pin harness connector (or directly cut this wire) and insulate the exposed part of the wire carefully.

FC Configuration

FC Firmware Update

SpeedyBee F405 V4 flight controller does not support wireless firmware flashing, so please flash firmware for it on your PC following the steps below:

1. Connect the flight controller to the PC with a USB cable
2. Open Betafight/ INAV configurator on your PC. Take Betaflight configurator as an example, go to the Firmware Flashing' page, choose the target 'SPEEDYBEEF405V4" and flash.

Note 2: The FC and ESC can also connected via direct soldering. Soldering pads definition is as follows.

ESC Configuration

• You could use the SpeedyBee APP to configure this ESC wirelessly for both BLHeli_S or Bluejay firmware. Steps:
  
• You could also use PC configurators to configure this ESC. We recommend the ESC Configurator. Please use Google Chrome browser and visit: http://www.esc-configurator.com.

ESC Firmware Update

• This 8-bit 55A ESC can run BLHeliS or Bluejay firmware. It is loaded with BLHeliS firmware by default. You could also flash it to Bluejay firmware which can support RPM filtering and Bi-directional Dhsot.

Firmware flashing steps are as follows:

• Remove all the propellers from your drone.
• Ensure that the flight controller is connected properly to the ESC, then power up the drone. This step ensures that the ESC starts up correctly.
• Connect the flight controller to the computer using a USB Type-C cable.
• Open the Chrome browser and visit the following website: https://www.esc-configurator.com
• Follow the firmware flashing steps as shown in the screenshots below.

On the 6th interface, the "ESC" type must be selected as "J-H-40".
