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.

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.
BOOT Button
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/INAV configurator on the PC, go to the ‘Firmware Flashing’ page, choose the target ‘SPEEDYBEEF405MINI’ and flash.

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.

Cable Connection vs DJI O3 Air Unit

Use the DJI 6-pin cable(80mm) comes with the F405 Mini stack(See the accessory No.6 in the
package section). Cut off the 8-pin connector and keep the 6-pin connector. Use the 6-pin connector to connect to the DJI O3 Air Unit, and then solder the other end to the flight controller.

Cable Connection vs RunCam Link/ Caddx Vista Air Unit

Use the DJI 6-pin cable(80mm) comes with the F405 Mini stack(See the accessory No.6 in the package section). Cut off the connectors on both ends and solder the 6 wires.

Cable Connection vs DJI Air Unit V1

Use the DJI 6-pin cable(80mm) comes with the F405 Mini stack(See the accessory No.6 in the
package section). Cut off the 6-pin connector and keep the 8-pin connector. Use the 8-pin
connector to connect to the DJI Air Unit V1, and then solder the other end to the flight controller.

Important notice for SBUS receiver

When using an SBUS receiver, the SBUS signal wire of the receiver must be connected to the SBUS pad on the front side of the flight controller (this pad internally uses UART2).

If you are also using the DJI Air Unit(O3/Link/Vista/Air Unit V1), 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.                                  Do NOT connect this wire to assure the external SBUS receiver work properly!

Important 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 SBUS signal wire 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.

For some ELRS receivers, it is necessary to disconnect this wire in order to function properly!

FC Configuration

FC Firmware Update

Speedy Bee F405 Mini 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 ‘SPEEDYBEEF405MINI’ and flash.

ESC Configuration

You could use SpeedyBee app to completely configure this 8-bit ESC for both BLHeli_S or Bluejay firmware. The steps are as follows:

You could also use PC configurators to configure this ESC. We recommend the ESC
Configurator. Please use Google Chrome browser and visist:http://www.esc- configurator.com.

ESC Firmware Update

This 8-bit 50A 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.escconfigurator.com/
• Follow the firmware flashing steps as shown in the screenshots below.
  Important note: On the 6th interface, the “ESC” type must be selected as “J-H-40”.
