◆Only the R5V pad can be powered via USB. To ensure easy debugging when the baery is not connected, the
5V wire of receiver must be connected to R5V instead of other 5V pads.
◆Please follow the diagram on this page to connect the desired type of receiver.

◆Most CAMs and VTXs supports a wide voltage range. For beer low-pass ltering performance, please connect
their power wires to the 9V pads.
◆The 9V remains ON in the inial state, it can be controlled ON/OFF by a PINIO funcon through the user1

◆An exclusive 10p cable for the ESC included in the package use to connect the two white connectors on the
back of them in front. In this case, It is not necessary to use the rear half-hole pads to supply power.
◆The telemetry output wire is connected to the RX5 by default.
◆You can also solder wires to the 9 half-hole pads in their front, but this is not necessary.

◆The RSSI pad mark SR compable analog signal.
◆The current sensor that needs to be used must rst know its output rao and the signal wire is connected to
the SI pad. The default rao of Ares F7 is 366.
◆Ares F7 is powered directly by the baery so it does not have a signal input pad. The onboard voltage divider is
congured to 110.

▸Power supply
TOP VIEW
◆Ares F7 supports 8 ~ 40V direct input voltage, due to the limitaon of DJI Air module and the stability of BEC
output voltage, 3 ~ 4 cells is usually recommended.
◆Ares F7 has 3 pairs of power and ground pads onboard, In the case of using Ares 4IN1 ESC in combinaon, the
rear pads do not need to be connected.
◆Only R5V pads can provide 5V to power a receiver with only USB power supply.
