SERVOS/CONTROLLERS
Monster Torque Servos
Hitec now offers two of their most technologically advanced "Monster Torque" servos.
Both of these powerhouse servos have premium
performance and durability. Each features a 7.4V
optimized coreless motor, integrated heatsink case, and a
top case with two hardened steel gear pins supported by
brass axial bushings. These servos are designed with
Hitec’s newest high resolution "G2.5" 12-bit programmable
digital circuit and indestructible titanium gears. The HS-
M7990TH utilizes a high resolution magnetic encoder
while the HS-7980TH employs a conventional
potentiometer.
The HS-7980TH and HS-M7990TH are ideal for high
performance giant scale aircraft, truggies and buggies,
monster trucks, and high performance boats.
Common Features:
• G2.5 12-bit Digital Programmable Circuit
• Titanium Gear Train (MK first gear)

Mini Maestro USB
Servo Controllers
Pololu has released the Mini Maestro 12-, 18-, and 24- channel USB servo controllers. In addition to a TTL
serial interface, these small boards incorporate native USB
control for easy connection to a PC and programmability
via a simple scripting language for self-contained, host
controller-free applications. The Maestros’ extremely
precise, 0.25 us resolution servo pulses have a jitter of less
than 200 ns, making these servo controllers well suited for
high-performance applications, and individual speed and
acceleration control for each channel allow for smooth,
seamless movements. The Mini Maestros feature
configurable pulse rates up to 333 Hz and can generate a
wide range of pulse widths to allow maximum
responsiveness and range from modern servos. Units can
be daisy-chained with additional Pololu servo and motor
controllers on a single serial line.
A free configuration and control program is available
for Windows and Linux, making it simple to configure and
test the board over USB, create sequences of servo
movements for animatronics or walking robots, and write,
step through, and run scripts stored in the servo controller.
The 8 KB of internal script memory allows storage of up to
approximately 3,000 servo positions that can be
automatically played back without any computer or
external microcontroller connected.
The Maestros’ channels can also be used as general-
