Mini Maestro 24 (kit) is a flexible controller for advanced applications with multiple servos, offering sophisticated motion control, signal reading, and autonomous operation capabilities. It is ideal for use in robotics, animatronics, and embedded systems as a precise controller and input/output expander.

This Kit with fully-dedicated PWM driver chip handles all the motor and speed controls over I2C. Only two data pins (SDA & SCL in addition to the power pins GND & 5V) are required to drive the multiple motors; you can also connect any other I2C devices or shields to the same pins. This  makes it drop-in compatible with any Arduino, such as the Uno, Due, Leonardo and Mega R3. Adafruit 1438

Mini Maestro 12 in kit version is a multifunctional controller for controlling servos, reading sensors, and executing motion sequences without a computer. Excellent for use in robotics, animatronics, and interactive systems, it enables flexible motion control and peripheral management from a PC or microcontroller.
