
In this manual, the direction for all the DIP switches is shown by
white color .
 the position for the DIP switch 1 is OFF, if it was put in ON, then the
FY-31AP cannot work normally.
 GPS features
The FY31AP GPS pin interface consist of: GND, 3.3V voltage, TX0, RX0.
The characteristics are:
 Baud Rate : 38400
 Interface Features: TTL level
 Data bits: 8
 Stop Bits: 1
 Parity: None
Connect the above to the GPS Receiver. The GPS data protocol is a
standard NEMA0183 and the statement must be $ GPRMC, $ GPGGA.
NOTE: The pin”I-1,2,3,4”is for the GPS module, “I-3”pin output
+3.3V, so please don’t supply to this pin, or will burn the
FY-31AP.
TXO pin interface is used to output FY-31AP (above firmware V2.1) data,
and connect Hornet-OSD (above firmware V1.6) .
Horner-OSD can be connected to the FY-31AP high-speed data outlet.
You need a 4p Y cable, the Hornet - OSD (above firmware V1.6).
data cable and GPS module connected to the FY-31AP( above firmware
V2.1) ’s GPS interface. Connection diagram is as follows:
 UART Interface
The UART pin interfaces consist of: GND, power, TX1, RX1. The
characteristics are as follow:
 Baud Rate: 19200
 Data bits: 8
 Stop Bits: 1
 Parity: None
 Interface features: TTL
The pin interfaces output telemetry data. This interface connects to the
data radio, PC computer serial port or OSD module. You can set the
flight route, navigation and control parameters of FY31AP by this
interface. The port is also used to upgrade FY31AP firmware.
Please read the procedure for the firmware upgrading.
 FY-31AP Electrical Connection and Diagram
a) Power supply
 The FY-31AP operates between 4 to 6 volts input.
 FY-31AP is powered via the Receiver connection.
 If your plane is Electric powered, the Receiver power supply is
normally from the ESC built-in Battery Elimination Circuit (BEC).
However, we highly recommend that a separate BEC with a 3A
output.
 For Gas or Nitro powered planes, you will require a battery to power
the Receiver and FY-31AP.
b) Connections The FY31AP is
connected to your RC Receiver
via a 6 wire cable. You need a
minimum 6 Channel RC
Receiver.
 FY-31AP requires a minimum
of 6-channel RC receiver.
 4 Receiver channels are used for aileron (channel 1), elevator
(channel 2) ，throttle (channel 3) and rudder (channel 4) signal
output. Connect these 4 receiver output signals to the FY-31AP with
the supplied wires (pay attention to the color of each channel ).
 2 free Receiver channels are required to control the FY-31AP Flight
Modes (3-position switch or dial knob, ”SW1”) and Autopilot
Mode (3-position switch or dial knob, ”SW2”).
