The A4988 Stepper Motor Driver is a microstepping motor controller capable of driving bipolar stepper motors up to 2A per coil with 1/16 microstepping resolution. Designed for Arduino, RAMPS, and CNC applications, it supports 8V–35V motor voltage and includes current limiting, over-temp, and short-circuit protection—perfect for 3D printers, CNC routers, and robotics projects.
The HW-687 Mini DC Motor Speed Controller is a compact PWM-based driver that allows smooth and precise control of DC motor speed. Operating from DC 3V–35V with a 5A maximum current, it’s ideal for DIY electronics, robotics, and Arduino-based projects, offering efficient motor control in a small form factor.
