Continuous rotation servos and standard servos!

Continuous rotation servos and standard servos are now in stock!


Contservo Lrg
Continuous Rotation Servo… This servo rotates fully forward or backwards instead of moving to a position. You can use any servo code, hardware or library to control these servos. Good for making simple moving robots. Comes with one horn only, as shown

  • Power 6vdc max (5V works best)
  • Average Speed 60 rpm (Note: with 5vdc and no torque)
  • Weight 45.0 grams/1.59oz
  • Torque 3.40 kg-cm/47oz-in
  • Size mm (L x W x H) 40.5×20.0x38.0
  • Size in (L x W x H) 1.60x.79×1.50

To control with an Arduino, we suggest connecting the white control wire to pin 9 or 10 and using the Servo library included with the Arduino IDE (see here for an example sketch). Position “0” (1.5ms pulse) is stop, “90” (2ms pulse) is full speed forward, “-90” (1ms pulse) is full speed backwards. They may require some simple calibration, simply tell the servo to ‘stop’ and then gently adjust the potentiometer in the recessed hole with a small screwdriver until the servo stops moving.
For more information, check out the Parallax Datasheet. Grab one at the Adafruit store.


Stdservo Lrg
Standard servo – This standard servo can rotate approximately 180 degrees (90 in each direction). You can use any servo code, hardware or library to control these servos. Good for beginners who want to make stuff move without building a motor controller with feedback & gear box. Comes with 3 horns, as shown. They aren’t the highest quality servo (which is why they are less expensive) and so are not suggested for hobby planes

  • Power 6vdc max (5V works best)
  • Average Speed 0.23 sec/ 60° (Note: with 5vdc and no torque)
  • Weight 39.2g (1.37 oz)
  • Torque @ 5V 3.20 kg-cm/45oz-in
  • Size mm (L x W x H) 40.6 x 20.0 x 38.9 mm
  • Size in (L x W x H) 1.60x.79×1.50

To control with an Arduino, we suggest connecting the orange control wire to pin 9 or 10 and using the Servo library included with the Arduino IDE (see here for an example sketch). Position “0” (1.5ms pulse) is middle, “90” (2ms pulse) is all the way to the right, “-90” (1ms pulse) is all the way to the left. In the Adafruit store.

    Can robot kits be far behind, hmmmm?

  2. …..maybe

  3. Have you tried modifying these to do 270 degrees rotation?
    You can add a resistor in parallel with the pot on some to give you more rotation.
    If you talk to Chip or Ken tell them HI for me!!!

    How about a Adafruit business card robot???
    Ala EvilMad Science style.
    L298 or servo pins ( population option ) with the rest being a usb boarduine ( pins down the side of the cpu for expansion cards )
    So much for my 2 cents worth 🙂
