The HSR-1425CR is the continuous rotation version of the HS-425HB
The speed is proportional meaning that the further the PWM signal deviates from the idle signal (approximately 1500usec) the faster the servo will rotate
If you're looking for the smoothest continuous rotation servo, be sure to check out the HSR-2645CR servo
4.5 – 24 Volt operation
11 pole encoder
Two solid state 3144 Hall effect sensors
100% Arduino compatible
Designed for 25mm DC motors
2 x Motor Encoders
2 x Metal mounts (for 25mm motors)
2 x Magnets
While regular servos that get modified to continuous rotation tend to be difficult to control the speed on, the HSR-2645CR circuit was designed from the factory to drive the servo smoothly and with fine-control over the speed
Since the HSR-2645CR servo is digital, it's able to be tuned using a Hitec servo programmer
The programmable parameters allow you to tailor the servo to best-fit your application
Excellent for compact sliders, winch mechanisms, small panning devices and wheel-drives on robots
Ideally suited for interfacing between low−level digital logic circuitry and high−power peripheral loads
High−voltage, high−current Darlington arrays in an 18−Lead DIP type package and feature peak load current ratings to 600mA for each of the eight drivers in each device
Typical loads include relays, solenoids, stepping motors, multiplexed LED and incadescent displays, and heaters
Mate with Arduino and Arduino compatible boards
