This is Pololu 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. 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 The Channel Settings tab in the Maestro Control Center. Free configuration and control application for Windows and Linux makes it easy to: 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) Upgradable firmware Package Includes: 1 x Pololu Mini Maestro 18-Channel USB Servo Controller (Assembled)
