Servo Trigger - a module for controlling a servo

An expansion board for the BBC micro:bit, allowing easy connection and control of low-power servos. It supports two servos by default, and up to three by disabling the built-in ZIP LEDs. Powered by three AAA batteries, it simultaneously supplies power to the micro:bit, while a power switch protects against unnecessary discharge. With five RGB ZIP LEDs and the ability to connect additional ones, the board allows for attractive lighting effects and is ideal for robotic projects like the :MOVE mini. Kitronik 5623

This module enables the Feather series range to be expanded with 8 12-bit PWM outputs that can be used, for example, to control servos or LED diodes. Adafruit 2928

The 8-channel servomechanism controller with potentiometers is a versatile device that allows you to control many servomechanisms at the same time. With a wide voltage range and resistance to extreme temperatures, it is an ideal solution for robotics projects and remote-controlled applications.

16-Channel 12-bit PWM/Servo Driver - I2C interface - PCA9685, RoHS

Servo control module with 180 degree range of motion, No programming required and is ideal for operations such as opening and closing the mouth, hands or eyes. Control is performed using the built-in ATTiny13A, button and potentiometer, and each pressed button moves the servo to the other end of the range, with the possibility of adjusting the length of the movement.

Module with a 16-channel PWM PCA9685 driver. The board is equipped with a Grove connector and communicates via the I2C interface. Seeed Studio 108020102

The board generates 16 PWM signals and communicates using the digital I2C interface, it has a built-in PCA9685 chip. MOD 71

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

Pololu Micro Maestro 1350 is a compact, versatile servo controller with a USB interface and autonomous operation capability, designed for use in robotics, animatronics, and control systems based on PCs or microcontrollers. Thanks to its flexible channel configuration, it can also be used as a sensor interface and I/O expander.
