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. 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 channel. Channels can be optionally configured to go to a specified position or turn off on startup or error. Alternate channel functions allow the channels to be used as. General purpose digital outputs 0 or 5 VAnalog or digital inputs channels 0 1. One channel can be a PWM output with frequency from 2. Hz to 1. 2 MHz and up to 1. Section 4. a for detailsA simple scripting language lets you program the controller to perform complex actions even after its USB and serial connections are removed. The Channel Settings tab in the Maestro Control Center. The Status tab in the Maestro Control Center. Free configuration and control application for Windows and Linux makes it easy to. Configure and test your controller. Create, run, and save sequences of servo movements for animatronics and walking robots. Write, step through, and run scripts stored in the servo controller. Two ways to write software to control the Maestro from a PC. Virtual COM port makes it easy to send serial commands from any development environment that supports serial communication. Pololu USB Software Development Kit allows use of more advanced native USB commands and includes example code in C, Visual Basic. NET, and Visual CTTL serial features. Supports 3. 00 2. Simultaneously supports the Pololu protocol, which gives access to advanced functionality, and the simpler Scott Edwards Mini. SSC II protocol there is no need to configure the device for a particular protocol modeCan be daisy chained with other Pololu servo and motor controllers using a single serial transmit line. Chain input allows reception of data from multiple Mini Maestros using a single serial receive line without extra components does not apply to Micro MaestrosCan function as a general purpose USB to TTL serial adapter for projects controlled from a PCBoard can be powered off of USB or a 5 1. V battery, and it makes the regulated 5. V available to the user. Upgradable firmware. Maestro Comparison Table. This is the weight of the board without header pins or terminal blocks. The available pulse rate and range depend on each other and factors such as baud rate and number of channels used. See Section 9 for details. The user script system is more powerful on the Mini Maestro than on the Micro Maestro. See Section 6. d for details. Application Examples. Micro Maestro as the brains of a tiny hexapod robot. Serial servo controller for multi servo projects e. BASIC Stamp, Orangutan robot controllers, or Arduino platforms. Computer based servo control over USB port. Computer interface for sensors and other electronics. General IO expansion for microcontroller projects. Programmable, self contained Halloween or Christmas display controller that responds to sensors. Self contained servo tester. Micro Maestro Pinout and 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. What to do When i. Tunes Wont Detect an i. Phone, i. Pad, or i.
