DFRobot DRI0057 Control Board – Serial Bus Servo Driver (9–12.6 V DC, up to 253 servos)

A compact servo controller based on the PCA9685 chip, allowing simultaneous control of up to 16 RC servos. The board features a built-in Edge Connector for direct connection to the micro:bit and Link-compatible pads for easy integration with other modules. Power can be supplied via the terminal block or servo connectors, and a built-in switch and LED simplify operation. The controller provides a stabilized 3.3V output for the micro:bit and additional devices, making it a perfect central module in your project. Kitronik 5694

16-channel servo driver module with I2C interface based on the PCA9685 system. modPCA9685

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

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

Universal tester of servos and ESC regulators. It allows you to check the operation of the servo without the need for a transmitter and receiver

Advanced servo controller with UART and USB communication, enabling precise control of multiple servos simultaneously. Compact design and stable power supply via screw connector make the device ideal for integration in robots and automation systems with limited space. Cooperation with the Seeed Studio XIAO ecosystem and the use of serial bus instead of traditional PWM provide efficient, scalable and reliable control in educational, research and DIY projects.
