USB Servokontroller 12 kanaler

The 12-channel Mini Maestro 12 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 (0.25 μs 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.

Main Features

• Three control methods: USB, TTL (5 V) serial, and internal scripting
• 0.25 μs output pulse width resolution (corresponds to approximately 0.025° for a typical servo, which is beyond what the servo could resolve)
• Pulse rate configurable from 1 Hz to 333 Hz ⁽²⁾
• Wide pulse range of 64 μs to 4080 μs ⁽²⁾
• Individual 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 V or 5 V)
  • Analog or digital inputs (channels 0 to 11 can be analog inputs; channels 12+ can be digital inputs)
  • One channel can be a PWM output with frequency from 2.93 kHz to 12 MHz and up to 10 bits of resolution
• A simple scripting language lets you program the controller to perform complex actions even after its USB and serial connections are removed
• Comprehensive user’s guide

The Channel Settings 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 C++
• TTL serial features:
  • Supports 300 bps to 200,000 bps in fixed-baud mode, 300 bps to 115,200 bps in autodetect-baud mode ⁽²⁾
  • Simultaneously supports the Pololu protocol, which gives access to advanced functionality, and the simpler Scott Edwards MiniSSC II protocol (there is no need to configure the device for a particular protocol mode)
  • Can 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 Maestros)
  • Can function as a general-purpose USB-to-TTL serial adapter for projects controlled from a PC
• Our Maestro Arduino library makes it easier to get started controlling a Maestro from an Arduino or compatible boards like our A-Stars
• Board can be powered off of USB or a 5 V to 16 V battery, and it makes the regulated 5 V available to the user
• Upgradable firmware
