Q: Green LED not ON when connected via USB.
A: Check USB cable.
Q: Green LED not lit when powered by battery.
A: 5V regulator damaged. Check board for short circuits/debris/solder-balls.
Q: Blue LED not lit.
A: 3.3V regulator or CPU damaged. Check board for short circuits/debris/solder-balls.
Q: Yellow LED not lit.
A: 12V regulator damaged. Check board for short circuits/debris/solder-balls.
Q: The status LED never lights or is always on.
A: Follow recovery procedure in the configurator. Likely caused by flashing wrong firmware.
Q: Unable to connect and a repeating light sequence occurs on the activity LED.
A: Check the Cleanflight manual for how to interpret the error code (count the long flashes).
Q: Unable to connect to the board (and status LED shows non-repeating pattern at boot-up).
A: Close all Chrome browsers and Chrome apps, retry. COM Port drivers not installed? Try connecting via dif-
ferent UART OR Reset the board to defaults using buttons OR reflash firmware using ‘full chip erase’.
Q: Transponder code not recognised by receiver.
A: Check IR LED orientation and light beam exit path. Ensure transponder enabled in software. Ensure transpond-
er code correctly configured.
Q: The COM port does not show up after flashing firmware or resetting the firmware.
A: Wrong firmware was flashed; Use SPRACINGF3OSD target and follow recovery steps in the Cleanflight Con-
figurator firmware flasher to restore the firmware.
A: FONT UPLOAD is in progress - connect camera to monitor the progress. 5 second pause, font upload, 5 sec-
ond pause, normal operation.
Q: You have a problem not listed here.
A: Reset and/or upgrade the firmware, try again, report issues via the forums - links are in the configurator on
the ‘Documentation & Support’ tab. Before contacting your retailer reflash with latest CLEANFLIGHT and double
check - perhaps the firmware you are using is old or incorrect?
Transponder
The SPRacingF3NEO features a IR LED transponder system. For optimum performance ensure you read the follow-
ing section. IR-LED available separately.
Mounting - Ensure that the IR LED can shine light from its installed location onto the track-side receiver, unobstruct-
ed. e.g. ensure that props, motors, arms, etc, are not in the way of the light shining from the LED.
Orientation - Ensure the LED points outwards from the aircraft towards the track-side receivers. The more receivers
you use the better the code reception will be.
Verifying operation - Ensure that the TRANSPONDER feature is enabled in Cleanflight. Ensure that the correct
pads of the IR/LED SELECT solder pads are bridged with solder. Ensure that the TRANSPONDER code has been
configured via the Race Transponder configuration section in the Cleanflight Configurator. Once this is done you
can use a CMOS/CCD camera without IR block pointed directly at the IR LEDs and you should see them pulsing.
A mobile phone camera works well for this, your FPV camera and screen/goggles may be OK if it doesn’t block
IR light.
Once you have verified that the IR LED pulses IR light then you can scan your SPRacingF3OSD/PDB past one of
the iLAP receivers. The iLAP receiver just needs power, no software configuration is required to verify that the
code is working.
The first time the iLAP receiver can read the transponder code the LAP light will pulse once, while the iLAP receiver
can read the code then the activity light (ACT) will be flashing.
Each time the LAP light flashes the receiver transmits transponder code and timing information via it’s COM port
