kk2.1 receiver pin voltages ?

Hi mate the kk board is powered off the motor 1 ESC and that is normally 5v dont power the board any other way ,than through the esc to be safe
 
dear holtneil,
receiver slots(throttle,elevation,etc) each has
3 pins(-ve,+ve and signal). My question is what is value for +ve voltage ?
 
Hi mate its the BEC voltage form the ESC so will be normally 5 volts its the same is if you had a servo on a receiver the servo will have a min and max volts it will work on , My Trex 500 pro has an esc that i can tell to run 5.5volts or 6 volts to the servos , but the volts come from the esc
look at the spec of the ESC you have it will tell you what output volts are if you cant find it give me a link for the ESC and i will have a look
 
okay that will help ! thanks alot !
one more query regarding receiver, what is the on time and off time of the pwm signal coming from receiver's end ?
 
Hi mate now you got me , i never need to get that deep into the board , what problem are you having
 
Hey Holtneil,
Actually i am making my quadcopter autonomous. So I am sending signals in receiver pins using my micro-controller(Atmega32), rather than sending it through radio transmitter !
 
You could look at the source for an Arduino based flight controller board. It should have the range of the rate that the com pin turns on and off.

This is what I could find

  1. ch1 = pulseIn(4, HIGH, 25000); // Read the pulse width of
  2. ch2 = pulseIn(5, HIGH, 25000); // each channel
  3. ch3 = pulseIn(6, HIGH, 25000);
  4. /*
  5. if(ch1>1000){Serial.println("Left Switch: Engaged");}
  6. if(ch1<1000){Serial.println("Left Switch: Disengaged");}
  7. Serial.print("Right Stick X:");
  8. Serial.println(map(ch3, 1000,2000,-500,500));
