PWM Control

PWM models take a standard RC servo signal, so any RC receiver, flight controller or microcontroller timer output drives them directly.

Parameter	Value
Pulse width	1000–2000 µs
Centre	1500 µs
Frame rate	about 50 Hz (20 ms period)
Supply voltage	3.6–10 V (1S or 2S LiPo direct)

To be confirmed

Wire colours, the exact travel per microsecond, and whether the servo accepts higher frame rates (e.g. 333 Hz) are not published yet. Ask us if you need them now.

Wiring

Wire	Function
Signal	PWM input
V+	Supply, 3.6–10 V
GND	Ground, common with the controller

Separate supply

Do not feed the servo from the controller's regulator. A stalling servo pulls enough current to brown out a microcontroller. Use a separate supply with a common ground, or add bulk capacitance close to the servo.

Example: Arduino

#include <Servo.h>

Servo s;

void setup() {
  s.attach(9, 1000, 2000);   // pin 9, pulse range 1000–2000 us
  s.writeMicroseconds(1500); // centre
}

void loop() {
  s.writeMicroseconds(1000);
  delay(1000);
  s.writeMicroseconds(2000);
  delay(1000);
}
