Failure to adhere to these warnings will void your warranty and destroy your flight
controller.
•
When using ESCs that support active braking or battery regeneration ensure the FC is protected with a
power supply filter. Damage to the FC caused by lack of protection is not warrantable.
•
Observe polarity at ALL TIMES.
Check
and
DOUBLE CHECK
before applying power. Do not rely on wire
color-coding alone.
•
POWER OFF
before unplugging, plugging in or making any connections.
•
Connect only one
5.0v
SOURCE of power to the
VIN
pins / Do not connect more than one SOURCE of
power to two or more of the
VIN
pins. e.g. If you are using ESCs with BECs then remove the center
RED
wire from all but one ESC connector.
•
Do not connect SOURCES of power to the pins marked with
5v
. They are OUTPUTS for supplying power
to other devices.
•
Do not connect a LiPo to the
5.0v
VIN pins.
•
The
3.3v
supply is for low-current use only. 100mA MAX.
•
Do not use a
VIN
voltage source higher than
5.0v
. Check your 5v supply is actually outputting
5.0 volts
,
check it before powering the FC via VIN. - Do not just assume it is 5v.
•
Do not connect GND,
5v
,
VIN
or
3.3v
to each other (short circuit).
•
Do not connect GND,
5v
,
VIN
or
3.3v
to any inputs or outputs unless specifically stated.
•
Do not connect any input or output to any other input or output unless specifically stated.
•
Do not allow dirt/dust/glue/etc into the pressure sensor (barometer).
•
Keep magnets away from the flight controller.
•
Do not use excessive force when inserting or removing MicroSD cards.
•
Always align USB plug and socket when inserting/removing USB cables to prevent damage to the USB
socket.
WARNINGS
GENERAL ADVICE
Follow the advice below for best performance and long-life of your flight controller:
•
Apply resin/glue to reinforce JST-SH connectors - helps if you crash your aircraft.
•
To further protect the board from crashes you can add a some additional solder to the edges of
the JST-SH and USB sockets to reinforce them.
•
Support JST connector sockets when inserting cables.
•
Using an enclosure/box for the flight-controller is recommended.
•
Install open-cell foam on the pressure sensor.
•
Do not cover the hole in sensor (e.g. with glue, resin, etc) or allow foreign object to enter it.
•
Route motor/battery wires as far away from the compass sensor (magnetometer) as possible.
•
Using color-coded pin headers is recommended (not supplied), especially for BATTERY connec-
tions.
•
For optimum performance do everything you can to prevent vibrations reaching the acceler-
ometer/gyro sensor. e.g. balance motors, props use rubber isolation grommets and secure
everything. If twitching is observed check motor bearings and other sources vibrations.

mounting compatibility with existing products such as the SPRacingF3OSD/PDB board.
Compared to the F3 EVO and F3 Acro/Deluxe the new F4EVO uses newer CPU, newer sensor technologies,
adds MicroSD and Transponder functionality and drops PWM receiver (1 wire per channel) support.
