Hardware advice ESP8266 NodeMCU V3

[bobblkabb]

Hello,

I would like to control several servomotors (approx. 15 motors) with a NodeMCU v3. These servomotors are to move small, perhaps 2-3cm large plastic elements.

Which components are recommended for this? How can I control several motors with one board, what do I need for this?
Which servo motors? As small as possible and low voltage would be practical.

Regards,
Michael

A PCA9685 board can drive up to 16 servos via a single I2C connection. There are libraries for MicroPython that support it: Servo.

You'll probably need a fairly powerful external supply to power all of those servos.

To control 15 servomotors with a NodeMCU V3, use a motor driver or shield for enough power, connect with jumper wires, and program with the Arduino IDE using the Servo.h library. Choose small, low-voltage micro servos for your project. Can dog eat

This is the MicroPython discussion, though ...
