Product description: Mini Maestro USB 24 channel servo controller - Pololu 1356
The Maestro series are versatile servo controllers also capable of interpreting digital and analog signals. With a variety of control options, a wide range of supply voltages, and simple operation, the Maestro works well for many projects using servos. Depending on the number of servos used, the user can choose the appropriate version. Available are 6, 12, 18 and 24 channel modules.
Product compatible with Arduino The manufacturer makes the library available on GitHub for Arduino users. |
Mini Maestro USB 24 channel servo controller - Pololu 1356.
Botland is an official distributor of Pololu electronics and robotics parts. Countless robots hold at least one component of this brand in their build. Our team guarantees that all Pololu products presented here are original.
Servo controller support
The user can customize the controller to the needs of his project, choosing from three different communication interfaces:
USB computer application - the device connects to the computer via a mini USB cable. An intuitive program is used to operate the controller, which allows, among others:
USB computer application features
- controlling the position of the orator
- setting the speed of servo rotation
- reading data from analogue and digital inputs
- setting the logical values at the I/O outputs
In order to use the USB control option, it is enough to download the program to disk (version: Windows, Linux), run it and connect the controller to any USB port of the computer.

Micro
Computer application that allows to control servo position and speed, read and write I/O statuses via USB cable.
Script - by selecting this option, the user can create and store the selected sequence of events in the Maestro memory, e.g. make the servo position dependent on the voltage level at the analog input to which any analog sensor is connected, e.g. a gyroscope, accelerometer or distance meter. A description of the scripting language together with examples of usage can be found on found in the manual.
Serial interface (UART) - the interface allows to connect Maestro to the central unit, which can be any microcontroller or runtime kit like Arduino, STM32Discovery or Rasbperry Pi. Servos are operated by sending special character commands. Examples along with a description of commands can be found in the manual.
Pololu Maestro controller pinouts
Pinouts are popular goldpin strips (raster 2,54), matching standard servo connectors and connection wires.
On the board you will find:
- MiniUSB connector used to connect the circuit to a PC
- 5V power rail pins to power other circuits
- Connectors for servo power supply (+ and -)
- Connectors for servomechanisms, the pin marked signal can also be used as analog inputs and digital inputs / outputs working with voltages of 5 V
- Status LEDs
- Power supply connector for logic circuits (useful if the controller will not be permanently connected to the USB port)
- Connectors for UART serial communication interface (RX, TX)

Examples of use
- Projects using many servomechanisms e.g. manipulator
- Walking robots e.g. Hexapods
- Controlling servos with a computer ( USB cable )
- Use of channels as general purpose digital outputs
- Use of analogue input channels e.g. for reading information from sensors (e.g. Sharp 10-80cm ) directly on a PC
- In versions 12, 18 and 24 one of the channels can work as a PWM output, so you can operate a motor driver (e.g. TB6612FNG)
