Description
Product Overview
The SmartDrive Mini L298N 2-Channel Motor Controller is a compact yet powerful dual H-Bridge driver designed for space-constrained robotics and DIY projects. While based on the reliable H-Bridge principle, this “Mini” version upgrades the traditional design by utilizing low on-resistance MOS switches instead of traditional bipolar transistors. This results in significantly lower heat generation, eliminating the need for bulky heatsinks in most applications .
This module serves as the perfect interface between your microcontroller (Arduino, Raspberry Pi Pico, STM32, ESP32) and your motors. It accepts standard logic-level signals to control direction and uses Pulse Width Modulation (PWM) for smooth, efficient speed control. Whether you are building a compact line-follower robot, a smart car, or a battery-powered toy, the SmartDrive Mini delivers robust performance in a tiny footprint .
Key Features
-
Dual-Channel H-Bridge: Independently control the direction and speed of two DC motors, or drive one bipolar stepper motor .
-
Compact & Lightweight Design: With dimensions of just 24.7mm x 21mm, this module is ideal for projects where space is at a premium .
-
MOSFET-Based Efficiency: Utilizes advanced MOS switches with low circuit resistance. This design runs cooler, requires no external heatsink, and is more power-efficient than traditional L298N linear driver boards .
-
PWM Speed Control: Dedicated enable pins allow for precise speed regulation via PWM signals from your microcontroller, giving you smooth acceleration and deceleration.
-
Integrated Thermal Protection: Features a built-in thermal protection circuit with hysteresis (TSD). If the motor stalls or the module overheats, the driver safely shuts down and automatically recovers once the temperature drops .
-
Wide Logic Compatibility: Signal input voltage range of 1.8V to 7V makes it compatible with both 5V and 3.3V microcontrollers without requiring level shifters .
-
Fail-Safe Inputs: Built-in common-mode conduction circuit ensures the motor does not malfunction when the input pins are left floating .
-
Low Standby Current: Consumes less than 0.1uA in standby mode, preserving battery life in portable applications .
