The accelerometer and gyroscope need to initialize e ery time the board is gi en power.
• Do not disturb the LUX board or your quad while powering on.
• Do not disturb the LUX board or your quad while plugging in.
• Wait until the initialization sequence is completed. When the acti ity LEDs settle, you
can mo e the quad/board.

BASICS
Hardware Setup
Make sure to select your RX input and logic le el by bridging the appropriate jumpers.
• Bridge only 3 for SPEKTRUM satellite.
• Bridge only 5 for Futaba, FRSKY S.BUS, ORANGE, etc. (no signal in erter needed).
• Select PPM for PPM, or SRX for Serial RX.
• The 3 jumper only changes oltage output for RX (pin #6 remains 5 ).
Connect ESC signal wires
• Connect the corresponding ESC signal wires to pins labeled 2 in the picture on page 2.
• Ground wires can be connected to the pins labeled 1.
Connect RX
• Connect PPM/SRX, 3.3-5V, GND to pins labeled 3.
Enable Telemetry
• Connect RX port on Recei er to selected TX pin on one of the USART pins labeled 5, 7, 8.
Enable feature in CLI: feature TELEMETRY
In the Ports tab in Cleanflight, select the Telemetry dropdown to output data on selected
USART.
Connect Buzzer
• Connect buzzer +/- to pins labeled 4.
Connect Blackbox De ice
OpenLog serial data loggers work o er simple serial connections and support microSD cards up to
64GB. Your LUX flight controller has 3 separate hardware serial (UART) TX/RX pin pairs.
• Connect VCC/TX/RX/GND to corresponding pins labeled 5, 6, 7, 8.
Enable feature in CLI: feature BLACKBOX
set blackbox_de ice = 0
In the Ports tab in Cleanflight, select the checkbox to enable Blackbox on the UART you choose. It
is recommended not to connect a wire from TX pin on OpenLog logger to RX pin on LUX.

6
Connect LED Strip
You can connect an addressable LED strip (WS2812B) to the LUX flight controller. Connect your
LED strip to pins labeled 12.
Enable feature in CLI: feature LED_STRIP
Connect Battery (Main Power connection)
Your LUX flight controller has input oltage 6-26 (2-6S lipo). Connect main power lead to pins
labeled 10.
 Always check the polarity before plugging in. There is no re erse polarity protection.
Enable feature in CLI: feature VBAT
Connect Current Sensor
Connect a current sensor signal wire to the pin labeled 9, and corresponding GND wire.
Enable feature in CLI: feature CURRENT_METER
current_meter_type 1
Connect OSD (On Screen Display)
You can connect a compatible OSD to your LUX flight controller. Connect the corresponding TX
and RX pins to USART1 labeled Pin 7.
For MWOSD and similar OSD, remember to change Voltage/Amperage/RSSI to “Use FC”.
Connect RSSI
Connect RSSI pin from your recei er to LUX pin 11
Connect GPS
GPS features in Cleanflight are experimental. Please share your findings with the de elopers. GPS
works best if the GPS recei er is mounted abo e and away from other sources of interference.
Connect GPS TX/RX/5 /GND pins to corresponding TX and RX pins (TX to RX, RX to TX) labeled
5, 6, 7, 8.
Enable feature in CLI: feature GPS
set gps_pro ider = 0 (nmea only)
set gps_pro ider = 1 (UBLOX only)

Software Installation/Setup
Hardware Dri er
Your Lumenier LUX has a Micro-USB connector. Hold the “boot” button while plugging in.
Windows users:
• Download Zadig from http://zadig.akeo.ie
• Open Zadig, choose Options > List All De ices
• Select STM32 Bootloader, WinUSB
• Click “replace dri er” or “install dri er”
Mac users:
Dri er will install automatically
Linux users:
Dri er will install automatically
Cleanflight Configurator
Cleanflight Configurator from the Google Web Store will be used to configure your Lumenier LUX
board.
• Download: http://chrome.google.com/webstore
Firmware Upgrade
Should Cleanflight Configurator stop working with your de ice, or your de ice becomes corrupted,
you can restore LUX to factory defaults with a standalone utility.
Windows users:
• Download: http://www.lumenier.com/LUXFlash.zip
Drag & Drop your firmware .hex fie onto LUXFlash.exe.
Mac & Linux:
• “DFU Util” “dfu-util” from the command line.

ADVANCED FEATURES
PID Stick Tuning (OSD)
MW OSD
Your LUX flight controller can be programmed ia stick positions, using your OSD (On Screen
Display) to display and change settings.
To access the OSD menu, make sure your LUX board is disarmed. Mo e the Throttle position to
middle, Yaw right, Pitch up. Change PID settings by using Pitch/Roll for selecting a alue, and
Yaw for changing the selected alue.

TROUBLESHOOTING
Firmware Upgrade
STM32 DFU MODE
Your LUX board can always be reco ered and restored to factory defaults should you e er
encounter software issues. Simply hold the “boot” button on your LUX board while plugging in the
USB cable. You can release the button after plugging LUX into your computer.
