The six-channel Micro maestro raises the performance bar for serial servo controllers with features such as a native USB interface and internal scripting control. Whether you want high-performance servo control (0.25Μs resolution with built-in speed and acceleration control) or a general I/O controller (E.G. To interface with a sensor or ESC via your USB port), this tiny, versatile device will deliver. The fully assembled version ships with header pins installed. Supports three control methods: USB for direct connection to a computer, TTL serial for use with embedded systems, and internal scripting for self-contained, host controller-free the channels can be configured as servo outputs for use with radio control or electronic speed controls, as digital outputs, or as analog inputs. Three control methods: USB, TTL (5V) serial, and internal scripting. 0.25Μs output pulse width resolution. Pulse rate Configurable from 33 to 100 Hz. Wide pulse range of 64 to 3280 μs. Individual speed and acceleration control for each channel. Size: 0.85" x 1.20". use USB a male to 5-pin USB mini-b cable.
