FEATURES

The 2-channels NODii-SERVO controller raises the performance bar for serial servo controllers with features such as a native UART and I2C 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 UART and I2C interface), this tiny, versatile device will deliver.

Main Features
Three control methods: I2C, TTL (5V) serial, and internal scripting 0.25µs 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 33 to 100 Hz (2)
Wide pulse range of 64 to 3280 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
A simple scripting language lets you program the controller to perform complex actions even after its I2C and serial connections are removed
Voltage BAT: 6-12V
Voltage for servo: 6-12V
