GWS S03N 2BB Standard-torque Ball-bearing Servo motor modified
for continuous rotation.
This is the same servo motor that's included in the Mark III Complete Kit,
except this one has been pre-modified for continuous rotation to
save you the time and trouble of doing that yourself.
This motor has two ball bearings for long life and smooth, quiet
operation.
Comes with accessory package which includes servo arms
and mounting hardware.
Motors are calibrated to produce zero rotation at 1.5 ms pulse
width. This zero point is user-adjustable - simply use a small
screwdriver inserted into the hole in the output shaft
to turn the potentiometer. The default calibration is
recommended for most usages.
