Batte input
1，FC BEC default output is 5.2V, supplied in two routes:
·The rst route is directly supplied to the 5V solder pads.
·The second route is supplied through a diode to the onboard chip and the
4V5 solder pads.
Please note that FC BEC can provide 2A continuous current and 3A peak cur-
rent. The onboard chip requires power ≤ 1A, GPS and receiver ≤ 0.1A, and wire-
less controller ≤ 0.1A. If connecting high-power telemet or VTX to the 5V
solder pads, ensure the operating current is ≤ 0.8A.
2，The VTX power supply inteace (Vv) can be set to two power ways: direct
batte power or internal BEC 5V (shared with 5V4A Seo BEC).
·Facto setting is batte power, where Vv inteace voltage is the same as
the batte voltage.
Please note: Ensure the voltage of VTX and camera power supply matches the
batte voltage, if not, damage may occur.
·By using VTX Power Supply Jumper, you can switch to 5V power supply. In
this case, the Vv inteace voltage will be 5V (if you choose this method, ensure
the seo and VTX current are sucient).
Please note: When Seo BEC Voltage Jumper is switched to 6V, the Vv inter-
face voltage also switches to 6V.
3，Seo power supply (Vx pin header) defaults to being powered by Seo
BEC at 5V. When Seo BEC is switched to 6V via Seo BEC Voltage Jumper,
the voltage at the Vx pin header also switches to 6V.
Please note that if the ESC suppos BEC output, do not connect the BEC red
wire to the Vx pin header. Otherwise, it may damage the ESC or Seo BEC.
Alternatively, you can directly power it using the ESC's BEC, but you need to
disconnect Seo BEC Power Supply Jumper. In this way, the power supply for
the Vx pin header comes from an ESC's BEC.
4，Power supply recommendations:
·When using a digital VTX with a wide voltage input, you can use the default
batte voltage for Vv.
·When using an analog VTX powered by 5V, you can switch Vv power supply
voltage to Seo BEC's 5V supply. In this case, you can install up to four 9g
seos to avoid insucient current.
·When using aircraft with 64 or 70 EDF Jets, Seo BEC power supply may not
be sucient for seos and landing gear. You can disconnect Seo BEC Power
Supply Jumper and directly use the ESC's BEC to power the devices.
