1.Features and hardware
MFD has build-in 3-axis gyro, 3-axis Acceleration sensor ，3 axis digital compass and
barometer. AP has two CPUs, one for the MFD attitude calculation, the other in charge for
the OSD and fly logic control. Base on this advance hardware, AP can be used for plane
stabilized, way point with altitude fly, and achieve autopilot and auto fly.
MFD AP’s advantage feature included:
1) Full attitude AHRS, max roll angular is 2000deg/s
2) Pixel-level black and white OSD, re-flash rate >30fps, no lag OSD flash
3) Intergraded MFD Auto Antenna Tracker (AAT) support, can use with MFD ATT directly
4) Through the OSD manual can setup and edit all parameters, and waypoint
5) Support MAVLink protocol, and can connect with third party open source ground station,
such as APM planner,

Connect to the device as the picture show below: put the MFD AP
connection pins facing to you
A) Power
This port will supply the power to the MFD AP. The AP has it own
voltage regulator, can be power from 7-20V, but the camera and the
video transmitter will also share the power directly from this port.
Most of the camera and video TX are 12V, so we recommend you to
power the MFD AP with 3S lipo, and will make the connection more
pretty and easy.
If you want to power up the MFD AP with 5V, leave the A1 (12
positive empty, no connection) and connect the ground (negative) to
the A2 pin. And the 5V positive connect to the servo output or the
receiver 5V input. Will show up in the picture below.

The servo output and the receiver power are not connected with
MFD AP. They are separated power from the MFD AP; you have to
supply power to the servo and the receiver.
B) CH1~CH6 Input
Connect to the RC receiver, as the picture show the top is signal and
the middle is power supply to the servo and the receiver, they are
internal connected. The bottoms are grounds they are internal
connected also. Power to this port will not power up MFD AP, if the
main power port is not connect to the power.

Mode switch A (2 postions)
CH6
Mode switch B(3postions )
MFD AP will need one two positions and one three positions switch to
switch the flight modes, The three position switch connect to the AP
CH6.
Use PPM receiver
MFD AP support PPM sum signal input, if you r receiver can output
PPM, then the connection is piece of cake, and using one servo wire will
provide all the signals to the MFD AP.
A) For Futaba serial receiver, PPM channel orders for channel 1-4 are AIL,
ELE, THR, and RUD. Use the jumper comes with the MFD AP,
connected to CH6, and then PPM signal to CH5.
B) For JR serial receiver, PPM channel orders for channel 1-4 are AIL, ELE,
THR, and RUD. Use the jumper comes with the MFD AP, connected to
CH5, and then PPM signal to CH6.
3 MFD AP will auto select the PPM order base on the jumper position。
C) CH1~CH4 Output
D) This port used for servo connections, use for control your airplane.
White color pin is signal pin, red is power positive, and black is the
ground. The red pins are internal connected to the receiver input
CH1-CH6.

G) Camera
Camera connecter (If you power AP with 12V, and camera is 12 V can
connect to it directly, make sure your camera are in the same power
range of the input power of the AP, they are internal connected)
