Mini Maestro 18-Channel USB Servo Controller Assembled
 

The 18-channel Mini Maestro 18 raises the performance bar for serial servo controllers with
features such as a native USB interface and internal scripting control.
Whether you want the best servo control available
(0.25μs resolution with built-in speed and acceleration
control and pulse rates up to 333 Hz) or a general I/O controller
(e.g. to interface with a sensor or ESC via your USB port), this compact, versatile device will deliver.
This fully-assembled version ships with header pins installed.
 

The Mini Maestros are highly versatile (and compact) servo controllers and general-purpose I/O boards.
They support three control methods: USB for direct connection to a computer,
TTL serial for use with embedded systems, and internal scripting for self-contained, host controller-free applications.
The channels can be configured as servo outputs for use with
radio control (RC) servos or electronic speed controls (ESCs), as digital outputs, or as analog/digital inputs.
The extremely precise, high-resolution servo pulses
have a jitter of less than 200 ns, making these servo controllers well suited for high-performance
applications such as robotics and animatronics, and built-in speed and acceleration
control for each channel make it easy to achieve smooth,
seamless movements without requiring the control source to constantly compute
and stream intermediate position updates to the Mini Maestros.
The Mini Maestros also feature configurable pulse rates from 1 to 333 Hz and can
generate a wide range of pulses, allowing 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 device 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 Mini Maestros’ 8 KB of internal script memory allows storage of up to
approximately 3000 servo positions that can be automatically played back without any computer or external microcontroller connected.

Because the Mini Maestros’ channels can also be used as general-purpose digital outputs and analog or
digital inputs, they provide an easy way to read sensors and control peripherals
directly from a PC over USB, and these channels can be used with the scripting system to enable creation of
self-contained animatronic displays that respond to external stimuli and trigger additional events beyond just moving servos.
