This PWM DC Motor Speed Controller (12V–40V, 10A) is designed to control motor speed smoothly and efficiently using Pulse Width Modulation (PWM) technology. It supports input voltages from 12V to 40V and outputs up to 10A current, making it perfect for DC motor control, DIY automation, fans, and smart electronics projects.
The Stepper Motor Driver Signal Generator (8V–24V) is a compact controller that produces precise pulse (PUL) and direction (DIR) signals for stepper drivers. With adjustable frequency and onboard potentiometers for speed control, it’s ideal for manually controlling stepper motors without the need for a microcontroller. Compatible with TB6600, TB6560, and other stepper drivers, this module is essential for CNC testing, prototyping, and automation setups.
The ULN2003 IC is a high-voltage, high-current Darlington transistor array in a DIP-16 package. It can drive stepper motors, relays, LEDs, and solenoids, making it ideal for Arduino, Raspberry Pi, and robotics applications.
