Turnigy 9X 2.4GHz 8Ch Receiver (V2) PWM to PPM

Introduction: Turnigy 9X 2.4GHz 8Ch Receiver (V2) PWM to PPM


Do you build copter? Do you have Turnigy reciever with 8ch PWM? Do you need PPM?

I have a simple solution!

Step 1: BUY and NEED

1) Turnigy 9x 2.4GHz 8Ch reciever (V2)

2) PPM Encoder Board

3) heat shring tube - diameter 19mm (37mm long)

4) solder

5) cutting spliers

6) tweezers

7) screwdriver

8) heat gun

Step 2: Try It Than to Disassemble!

First, I recommended you try if it works! Connect all channels as you can see in the picture.

PPM encoder pinout for sure:


1) GND - black

2) 5V - red

3) 1.pwm channel - white

4) 2.pwm channel - orange

5) 3.pwm channel - yellow

6) 4.pwm channel - green

7) 5.pwm channel - blue

8) 6.pwm channel - purple

9) 7.pwm channel - brown

10) 8.pwm channel - grey


1) GND - black

2) 5V - red

3) PPM - white

Step 3: Disassembly

Disassemble the reciever. You unscrew the two small screws and carefully remove the cover. You can get out the PCB carefully from case. You can take back side (the antenna side) slightly up and pull PCB.

Step 4: Removing Connectors and Soldering

Now it is nessesary to remove the conectors (dupont). You can take a cutting pliers and cut wires how long is needed to placement to next side. Make them longer by 2-3mm , for sure.

Shave end of the wire around 2mm.

All the ends of wire solder tin little. Solder the wires as shown in piucture on the PCB very carefully!

Slide heat tube to PPM encoder and warm up for shrinkage.

Step 5: Assembly

Put reciever PCB with new PPM enc.PCB back to case as picture shown. OUTPUT must go first.

You must conect 3 pins to Flight controller -

red 5V (power for boths PCB)

black GND (power for boths PCB)

white PPM.

PWM pins on receiver will be empty! Power for receiver is taken from PPM encoder.

Now you can try it!

Good luck!

    For any future readers, I did the same using an Arduino Pro Mini as the encoder:


    Make connections as shown in the blog: https://oscarliang.com/build-pwm-ppm-converter-arduino-2-4ghz-receiver/

    I used the ArduPPM encoder firmware which is actually for their PPM encoder (http://ardupilot.org/copter/docs/common-ppm-encoder-8-channel-standalone-encoder.html) but works well for the Arduino Pro Mini as well.

    Download the .hex file for their firmware (ArduPPM for ArduCopter), and flash it using an USBasp programmer and programming software (like SinaProg). Connections are made for programming as shown here: http://samopal.pro/wp13_samopal/wp-content/uploads/561/cxema.jpg
