I added this vibration motor to my Devo 6S and it's working very nicely. The circuit above was easy to source and assemble. The actual soldering to my Devo6S processor was, well, challenging given the risk, but in the end it wasn't that hard. The end results are awesome. I don't understand why Walkera left out the vibration.

Anyway, here are the pieces I used:
Cell Phone / Toy Micro Vibrator Motor w/ Mounting Bracket / Cable / Plug- 3 V DC ( www.ebay.com/itm/271913733382?_trksid=p2...e=STRK%3AMEBIDX%3AIT ) This motor included a frame with metal "wings" that would normally attach to the processor board. I bent one of them out about 90 degrees and it fit comfortably on one of the mounting screws.
BD237 Transistor (Digikey) - the E pin connects to ground.
1N4148 Diode - I connected the anode end and the black motor wire to the middle pin of the BD237; note the band (cathode end) should face AWAY from the transistor. On the cathode side of the diode I connected the red wire for the motor as well as Vdd (3.3v).
220 Ohm Resistor - I connected one side of this resistor to Pin 83 of the Devo6S processor, and the other to the Base of the Transistor.
30-gauge wire & shrink wrap




I also made use of Kapton tape to isolate the one processor pin that I wanted to connect. This helped a lot and along with the flux paste probably avoided having a sorry ending.

The wiring diagram above is exactly right. Here's what it looked like for me.



I edited the Hardware.ini file to enable the Haptic by removing the semi-colon (";") from that line "enable-haptic=1" and cycled the power on the Devo. However there were no vibrations. Then I remembered that you also need to turn on vibration in the transmitter configuration tx.ini file "vibration=1". This because in the Devo 6 and 8 there is no menu for Vibrate on/off and volume; the Devo 7e and 10 have the menu option because they have a native vibrator. The next time I powered on, I got good vibrations!

Devo6s 2x2 switch mod, trim mod, haptic, multimodule, A7105, NRF24L01, CC2500
Devo12e 4-in-1 with voice mod -- it speaks!!

Hi everyone,
Does anyone know if this mod is suitable to make it on a 12S?

Thanks!

12S need a different pin, and some mod in the code.

It's very old post. But I still want to say it's really easy to replace https://www.vibrationmotors.com/product-guide/the vibration here as the voltage is 3V DC
