1. How to Set a SBUS receiver
If you’re planning to use a SBUS receiver, please solder the GND/Power/Signal Wire of the receiver to the GND/5V/RX1points on the FC first, then push the “Serial Rx” option button under
“UART1” from Gray to Yellow on the “Ports Interface” of the Betaflight software, and set the “Receiver Mode”, “Serial Receiver Provider” on the receiver to “Serial-based Receiver”,
“SBUS” respectively on the “Configuration Interface” at last.
2. How to Set a Spektrum 1024/2048 Receiver
If you’re planning to use a Spektrum DSM2/DSMX receiver, then please solder the GND/Power/Signal Wire of the receiver to the GND/3.3V/RX1 points (on the FC) first, and then push the
“Serial Rx” option button under “UART1” from Gray to Yellow on the “Ports Interface” of the Betaflight software. And set the “Receiver Mode”, “Serial Receiver Provider” on the receiver
to “Serial-based Receiver”, “SPEKTRUM1024/2048 (1024 for DSM2, 2048 for DSMX)” respectively on the “Configuration Interface” at last.
How to bind the Spektrum receiver and transmitter:
Please key in the following codes on the CLI (Command Line Interface) of the Betaflight software.
• Key in “set spektrum_sat_bind= 9, and then press the “Enter” button on the keyboard.
• Key in “set spektrum_sat_bind_autorst= 0, and then press the “Enter” button on the keyboard.
• Key in “save”, and then press the “Enter” button on the keyboard.
Please wait for the FC to restart, disconnect the FC from all the power supplies (including the USB port), and re-connect the FC to the power supply, then you can see the LED on the
Spektrum satellite receiver flashes rapidly, turn on the transmitter to bind the transmitter and receiver. If the LED dies out and then comes on solid, then it means that the binding is
succeeded. Otherwise, change the number in the code “set spektrum_sat_bind = 9” to any other number (from 1 to 9) and try again.
Please connect the FC to the Betaflight software, and key in the following codes on the CLI (Command Line Interface) of the Betaflight software after successfully binding the transmitter
and receiver.
• Key in “set spektrum_sat_bind = 0”, and then press the “Enter” button on the keyboard.
，
• Key in “save”, and then press the “Enter” button on the keyboard.
After that, you can use your spektrum satellite receiver to receive signals.
You need to enter the so-called “DFU” mode when flashing the FC firmware. A software tool called Zadig (you can download it from this website: http://zadig.akeo.ie/) will be needed to
switch the driver (of the FC) to the “DFU” mode. In order to switch the driver, you need to take the following steps.
How to this FC to Connect Dif ferent Receivers
06
In CLI: Type:
resource
Locate UART TX/RX pad resource ID you are using. We wired to RX5 in this demo. RX5 is D02 Note the name of resource and ID.
“ resource SERIAL_RX 5 D02 ”
Next we will clear that pad from its assigned resource.
Type:
resource SERIAL_RX 5 NONE
Next we need to assign the Resource ID to the Custom Mode switch. Using the Resource ID from above. "D02"
Type: resource PINIO 1 D02
Type: save in CLI and then press enter. Your FC will reboot after applying changes.
Now go to Modes and Assign an AUX channel to the USER1 mode. Just like an arm or turtle mode switch. Click SAVE.
Now you can control VTX power (10V) turn on or turn off with your transmitter .

How to Adjust Parameters
The Betaflight software (as shown below) is needed whether you’re planning to adjust parameters (of the FC) or flash firmware, you can download it from this website: https://github.com/Betaflight.
You need to run this software in Google Chrome, because it’s an extended software of Google. In regard to the software, you can download it from the Google App Store or this website:
https://github.com/betaflight/betaflight-configurator.
After connecting the FC to a computer, you can click to enter relevant web pages (as shown below) and download the software if you need.
You can start to adjust relevant parameters after you successfully connect the FC to the Betaflight software.
Please visit the following websites to download the latest version of Betaflight software:

•
Read through this user manual before use.
•
Ensure all wires and connections are well insulated before connecting the unit to
related devices, as short circuit will damage it.
•
Please ensure to solder all the wires & connectors well and not get soldering tin on any
electronic components if necessary. We won’t be responsible for any damage resulting
from soldering and installation.
•
Never use the joint pins beyond the ones included in the product box to fix or connect
the FC (Flight Controller), ESC and image-transferring board because the heights from
pins to sockets between image-transferring board and FC, FC and ESC board is
regulated/fixed. If the joint pins are too short, then they will cause the PCBs to deform;
if they are too long, then they will affect the connection between pins and sockets and
cause damage to relevant devices. We won’t be responsible for the damage or losses
resulting from users’ carelessness.
•
Never fly the aircraft near crowd; we won’t assume any losses resulting from the crash
of the aircraft.
•
Never use this unit near heat, moisture, strong acid or alkali and under other
environmental conditions that bad for electronic components.
•
The unit is ready-to-use (it’s flashed with firmware before leaving the factory), we won’t
be liable for any damage resulting from firmware flashing which is carried out by users.
•
The FC firmware is an open-source program, users can search relevant technical
information on the internet and we won’t provide any technical support beyond the FC
hardware.
•
This user manual is based on the operation manual for Betaflight and only for
reference. For more detailed information, please refer to the original Betaflight
manual. Due to firmware update or other reasons, the descriptions for functions may
differ, so please always take the official Betaflight manual as standard.
