Product description: Micro Maestro USB 6-channel servo controller - Pololu 1351
Micro Maestro is a controller from Pololu that allows you to control RC servos and ESCs from a computer via USB or from embedded systems via a 5V TTL serial interface . Additionally, it supports stored scripts, enabling the execution of motion sequences and control logic without a permanent connection to a PC or microcontroller . Each of the 6 channels can be configured as a servo output, digital output, or analog input . High 0.25μs pulse resolution and very low jitter make the module ideal for robotics and animatronics applications where smooth and repeatable movement is essential. Power can be supplied from USB or an external source from 5V to 16V , and the connectors in this version of the kit are supplied separately to facilitate the installation of custom connectors. A USB A to mini-B cable (not included) is required for connection to a computer.
Arduino compatible product
The manufacturer makes the library available on GitHub for Arduino users.
Micro Maestro USB 6-channel servo controller - Pololu 1351.
Pololu Micor Maestro can be used, among others, in the construction of walking robots.
Main features of the servo controller

Servo driver pins
The pins are popular goldpin strips (2.54 pitch), fitted to standard servo connectors and connecting cables.
The board contains:
- miniUSB connector for connecting the system to a PC
- 5V power rail pins for powering other systems
- connectors for connecting power to servos (+ and -)
- connectors for servos, pins marked as signal can also be used as analog inputs and digital inputs/outputs operating with 5 V voltages
- status LEDs
- logic circuit power supply connector (useful if the controller will not be permanently connected to the USB port)
- UART serial communication interface connectors (RX, TX)
A - USB mini-B connector, B - 5 V (out), C - GND, D - signal, E - servo power supply, F - channel 0, G - channel 1, H - channel 2, I - channel 3, J - channel 4, K - channel 5, L - yellow and red status LEDs, RST - board reset, TX - TTL serial output, RX - TTL serial input, VIN - 5 V to 16 V board power supply, M - green USB LED
The set includes goldpin strips for self-assembly.
