Description
A4988 Stepper Motor Driver Module (Normal Quality) with Heatsink
📝 Description:
The A4988 Stepper Motor Driver is a complete microstepping driver with a built-in translator, making it extremely easy to control bipolar stepper motors. It supports full-step to 1/16 microstepping modes, allowing for smooth and precise motion control.
Operating between 8V and 35V, and delivering up to 1A per phase without heatsink (up to 2A per coil with cooling), it’s ideal for 3D printers, CNC machines, and robotics. With automatic current decay mode detection, mixed decay control, and onboard thermal, under-voltage, and short circuit protection, the A4988 is a compact and reliable solution for stepper motor control.
⭐ Key Features (Short):
-
🔁 Supports 5 step modes: full, 1/2, 1/4, 1/8, 1/16
-
🔌 Operating voltage: 8V to 35V
-
⚡ Up to 2A per coil with proper cooling
-
🧠 Built-in translator for easy step/direction control
-
❄️ Automatic current decay (slow/mixed mode)
-
🔥 Thermal shutdown and short-circuit protection
-
🔒 Under-voltage lockout (UVLO)
-
⚙️ Internal synchronous rectification for low power loss
