The Maestros are Pololus second generation family of USB servo controllers.The Maestro family consists of four controllers, each available fully assembled or as a partial kit With three control methods USB for direct connection to a PC computer, TTL serial for use with embedded systems, and internal scripting for self contained, host controller free applications and channels that can be configured as servo outputs for use with radio control RC servos or electronic speed controls ESCs, digital outputs, or analogdigital inputs, the Maestro is a highly versatile servo controller and general IO board in a highly compact package. Core Parking Manager Windows 10 . The extremely precise, high resolution servo pulses have a jitter of less than 2.Maestro well suited for high performance animatronics, and built in speed and acceleration control make it easy to achieve smooth, seamless movements without requiring the control source to constantly compute and stream intermediate position updates to the Maestro.The Maestro features configurable pulse rates up to 3.Hz for Mini Maestros and can generate a wide range of pulses 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 see Section 4, 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 Maestros internal script memory allows storage of servo positions that can be automatically played back without any computer or external microcontroller connected see Section 6.The Maestros channels can also be used as general purpose digital outputs and analog or digital inputs, providing an easy way to read sensors and control peripherals directly from a PC over USB.These inputs can be used with the scripting system to enable creation of self contained animatronic displays that respond to external stimuli.A USB A to mini B cable not included is required to connect this device to a computer.Features. Three control methods USB, TTL 5 V serial, and internal scripting.Configurable pulse rate and wide pulse range see the Maestro comparison table belowIndividual speed and acceleration control for each

Components.Micro Maestro 6 channel USB servo controller fully assembled labeled top view.Note This section applies to the Micro Maestro servo controller.Please see Section 1.Mini Maestro pinout and component information.The Pololu Micro Maestro 6 channel servo controller can connect to a computers USB port via a USB A to mini B cable not included.The USB connection is used to configure the servo controller.It can also be used to send commands to the servo controller, get information about the servo controllers current state, and send and receive TTL serial bytes on the TX and RX lines.Micro Maestro power pins.The processor and the servos can have separate power supplies.Processor power must come either from USB or from an external 51.V power supply connected to the VIN and GND inputs.It is safe to have an external power supply connected at the same time that USB is connected in such cases the processor will be powered from the external supply.Note that if the external supply falls below 5 V, correct operation is not guaranteed, even if USB is also connected.Servo power connections are provided in the upper right corner of the Micro Maestro board.Servo power is passed directly to the servos without going through a regulator, so the only restrictions on your servo power supply are that it must be within the operating range of your servos and provide enough current for your application.Please consult the datasheets for your servos to determine an appropriate servo power source, and note that a ballpark figure for the current draw of an average straining servo is 1 A.Micro Maestro configured to use a single power supply for both board and servos.You can power the Maestros processor and servos from a single power supply by connecting the positive power line to both VIN and the servo power ports.An easy way to accomplish this on the Micro Maestro is to solder a wire on the bottom of the board between VIN and one of the servo power connections as shown in the picture to the right.Only one ground connection is needed because all ground pins on the board are connected.
