Mini Maestro 24 Channel USB Servo Controller

Mini Maestro is a very compact versatile servo controller and general purpose I/O board. It supports three control methods: USB for direct connection to a computer, TTL serial for use with embedded systems, and internal scripting for standalone, host controller-free applications. Channels can be configured as digital outputs or analog inputs for use with radio controlled (RC) servos or electronic speed controls (ESCs). Highly accurate, high-resolution servo pulses have a jitter of less than 200 ns, making these servo controllers suitable for high-performance applications such as robotics and animatronics, and facilitating built-in speed and acceleration control for each channel. Achieve smooth, uninterrupted movements without requiring constant calculation of the control source and transfer of intermediate position updates to the Mini Maestro. 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, enabling the device to be configured via USB and It makes it easy to test, create servo motion sequences for animatronics or walking robots, and write, walkthrough, and execute scripts stored in the servo controller. Mini Maestros' 8 KB internal script memory allows storage of approximately 3000 servo positions that can be played automatically without any computer or external microcontroller connected.

Since the Mini Maestro's channels can also be used as general-purpose digital outputs and analog inputs, they provide an easy way to read sensors and control peripherals directly from a PC via USB and It can be used with the command system to enable the creation of these channels.

 

• Three control methods: USB, TTL (5 V ) serial and internal script
• 0.25μs output pulse width resolution (corresponding to about 0.025° for a typical servo, which is beyond what the servo can resolve)
• Pulse 1 Hz to 333Hz adjustable between
• Wide pulse range between 64 μs - 4080 μs
• Individual speed and acceleration control for each channel
• Channels can optionally be configured to go to a specific position or turn off on startup or error
• Channels can also be used as general-purpose digital outputs or analog inputs

• Free configuration and control application for Windows makes it easy to:

1. Configure and test your controller
2. Create servo motion sequences for animatronics and walking robots, run and store
3. Write, step and run scripts stored in the servo controller
    

• Two ways to write software to control Maestro from a computer:

1. Virtual COM port makes it easy to send serial commands from any development environment that supports serial communications< /div>
2. The Pololu USB Software Development Kit allows the use of more advanced native USB commands and includes sample code in C#, Visual Basic .NET and Visual C++.
    

• The board can be powered by USB or a 5V to 16V battery, making the regulated 5V available to the user.
• Compact size of 1.10"×2.30" (2.79×5.84cm) and 6g weight with heads
