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 LEDs connected to LED1-LED4 connectors on the bottom side are controlled by Betalight firmware(BF_LED mode) or the Bluetooth Chip(SB_LED mode).
Solid Orange ： indicates 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 Betalight firmware.

Long press the button for 3 seconds to switch the control modes between BF_LED mode and SB_LED mode.

FC’s Peripheral Connection

Wiring Diagram
Method 1 – Direct Soldering

Method 2 – All connectors
To recognize the wires in the package better, we marked some of these wires with letters(from A to F). Please find the right wires according to their letters.

Importance 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

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 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!

Cable Connection vs DJI O3 Air Unit
Use 6-pin cable comes with the O3 Air Unit

Cable Connection vs RunCam Link/ Caddx Vista Air Unit
Use 6-pin cable comes with the F7 V3 stack (See the accessory No.3 in the package section)

Cable Connection vs DJI Air Unit V1
Use 6-pin cable comes with the F7 V3 stack (See the accessory No.3 in the package section)

Part 3 – SpeedyBee BL32 50A 4-in-1 ESC

Connection with Motors & Power Cable

Note: In order to prevent the stack from being burnt out instantaneous voltage spikes on powering up, it is strongly recommended to use the Low ESR capacitor in the package.

ESC Conifguration & Firmware Update

• This ESC is a 32-bit ESC running BLHeli32 firmware inside. Since the BLHeli32 is close-sourced. So ESC configuration & firmware update can’t be done wirelessly in the Speedy Bee app. Please download the latest BLHeliSuit32 configurator to setup your ESC at https://github.com/bitdump/BLHeli/releases.
• Even so, you could still change motor directions in the app for this ESC. Please connect to the app, go to Motors page, click the button shown below. Then experience the easiest and coolest way to change motor directions.
