Pan - PWM3
Tilt - PWM4
Home button to PWM5. NOT working
Select button to PWM6. NOT working
Display to I2C port
Bluetooth to UART1
Local GPS to UART2


1. Short bootloader pins (Boot headers (11) - check pdf from link above), connect Usb.
2. Using Betaflight or Cleanflight configurator in Chrome upload SPRACINGF3_**.hex FW from here


1. Download and install Configurator from here
2. Run Configurator from Chrome Apps. Select Com port, select Bauds 115200, press Connect. Press CLI ENTER. Now all parameters should get loaded. Set in settings PROTOCOL to Autodect, and set BAUDRATE same as your bluetooth or radiomodem speed. I use 57600 for Mavlink. Press SAVE. To connect again to Configurator set Bauds to 57600 at the top.

Tip: Uart1 is in parallel with Usb, and it means telemetry is not coming in when Usb connected. You can connect a Bluetooth module to uart1. Usb is only useful for flashing new versions. You can, may and should configure/tune the tracker «wirelessly».

If not set by default, run the following command in CLI mode to be able to use the local gps function through serial port 1 (UART2):
serial 1 2 38400 38400 0 115200

Other settings should be like this for Ublox GPS:
set gps_provider=UBLOX
set gps_sbas_mode=AUTO
set gps_auto_config=ON
set...Continue Reading

Omnibus F4 Pro V3
2 UARTs since UART3 is always used for I2C in Ardupilot firmware
Sport support does not really exist yet
rssi solder pad to PIN 0 on omnibusf4pro, can be used for either ana rssi, ana arspd or any other analog voltage function desired.

PWM5 and 6 are pwm outputs, functions is set by SERVO5 and 6 function param

F405 Wing
UARTn = SERIALn except for USART2 being used for RCInput, so SERIAL2 stays empty
RSSI pin voltage is 0-3.3 v
the SD card reader is very picky (I had also trouble with logging) They stated that only 50% of the cards work for no apparent reason
non-inverted s.port

F411 won't be supported. F411 flash memory is too small to support ardupilot firmware.


internal compass
s.port is working
wing FC10 has an inverter on board for TX6. It is prepared to connect SmartPort.

and similar

QLrs faq + info

Flashing tips

QLRS FW supports E32-TTL-1W and E32-TTL-100 HW + similar 868 modules

Maximum range of this LRS has not been tested yet. You are welcome to be the first who will find this out.
QLRS supposed to provide better range than any other LRS that uses FSK modulation such as OpenLRS, ULRS etc.

Telemetry data is transmitted from UAV to ground station only! There is no full duplex link and it's not expected.

QLRS does not support full mavlink. The mavlink data is "converted" to some internal protocol, sent to the ground, and then mavlink message is resumed there.
Thus, the following messages (correctly the fields) that FC sends to QLRS are interpreted.
Then the same message is generated on the ground and they reach the software that displays the map, etc. etc.

When I decide to stop development and there will be some not fixed bugs, i will release source code, don't worry.
If you are interested in any particular piece of coding i can share it no problem...
