Frequently Asked Questions - Beecore BL F3 1S HappyModel

How to connect an SBUS receiver to the Beecore BL F3?

Connect the SBUS receiver to the [RCIN +5V GND] port. In Betaflight configurator, enable Serial RX on UART3, select Serial-based receiver as the receiver mode, and set the Serial Receiver Provider to SBUS.

How to connect a PPM receiver to the Beecore BL F3?

Connect the PPM receiver to the [RCIN +5V GND] port, then in Betaflight configurator, set the Receiver Mode to RX_PPM.

How to connect a DSM2/DSMX receiver to the Beecore BL F3?

Connect the receiver to the [RCIN +3.3V GND] port. Enable Serial RX on UART3, choose Serial-based receiver, and select SPEKTRUM1024 for DSM2 or SPEKTRUM2048 for DSMX in the Serial Receiver Provider.

How to connect a FlySky IBUS receiver to the Beecore BL F3?

Connect the IBUS receiver to the [RCIN +5V GND] port. In Betaflight, enable Serial RX on UART3, set the receiver mode to Serial-based receiver, and select IBUS as the Serial Receiver Provider.

How to flash the firmware of the Beecore BL F3 flight controller?

Install the STM32 Virtual COM Port and STM BOOTLOAD drivers. Open Betaflight configurator, choose the target OMNIBUS. To enter DFU mode, solder the BOOT pad or start the flash. Use Zadig to replace the STM32 Bootloader driver with WinUSB if necessary, then reconnect the board and flash the firmware.

How to update the ESC firmware via BLHeliSuite?

Download the latest version of BLHeliSuite. Connect the board to the PC and plug in a 1S battery. In Device Manager, check that the COM port number is lower than 255. Open BLHeliSuite, select SILABS BLHeli Bootloader (Cleanflight), choose the correct COM port, then connect to flash the ESCs.

What battery should be used with the Beecore BL F3?

The flight controller and ESCs accept a 1S LiPo/LiHV battery with a voltage between 3.6V and 4.35V. Make sure the battery can supply the required current (5A continuous per motor).

How to power the video transmitter (VTX) with the Beecore BL F3?

If you use a VTX with power greater than 25mW, it is recommended to power it with an external battery to avoid overloading the integrated BEC. For a 25mW VTX, you can use the +5V output of the controller.

Which ESC protocols are supported by the Beecore BL F3?

The ESCs support D-shot150/300/600, Oneshot125, Multishot, and PWM.

Does the Beecore BL F3 have an integrated OSD?

Yes, it has an integrated OSD interface that allows flight information to be displayed directly in the FPV camera.

2.VTX suggest to use a 25mw VTX, if you want to use a higher power VTX,

please use a external battery to power for the VTX.

Firmware update:

1. Install latest STM32 Virtual COM Port Driver http://www.st.com/web/en/catalog/tools/PF257938
2. Install STM BOOTLOAD Driver (STM Device in DFU MODE)
   3.Open Betaflight configurator and choose firmware target "OMNIBUS", then select the firmware version
   4.There are 2 ways to get in DFU Mode: 1). solder the boot pad and then plug USB to comuper 2). loading betaflight firmware and hit "flash", then it will getting into DFU Mode automatically
3. Open Zadig tools to replace the drivers from STM32 Bootloader to WINUSB Driver

1. Reconnect the flight controller to the computer after replace driver done, and open Betaflight configurator, loading firmware and flash.

Receiver configuration:

1.SBUS Receiver:

Connect your SBUS receiver to [RCIN +5V GND] port; Enable Serial_RX for UART3 from the Port tab in Betaflight configurator, then select SERIAL-based receiver from the RECEIVER Mode and set the Serial Receiver Provider to be SBUS in Betaflight Configurator.

2.PPM Receiver:

Connect your PPM receiver to [RCIN +5V GND] port and then set the Receiver Mode to RX_PPM from the configuration in Betaflight configurator.
