SPIDER Automation L9110S Dual Channel Motor Driver Board 2.5V-12V 0.8A | Motor Driver Module | Miniature Robotics DC & Stepper Control
Description
SPIDER Automation L9110S Dual Channel Motor Driver Module is an ultra-compact board tailored for driving miniature robots and low-voltage actuators. Featuring two independent L9110S motor driver chips, each capable of supplying up to 800mA of continuous current, this module handles light mechanical loads with ease. Operating seamlessly from 2.5V to 12V, it interfaces smoothly with both 3.3V and 5V microcontrollers such as Arduino, ESP32, and STM32 boards. Motor speed can be regulated using PWM (Pulse Width Modulation) signals, while simple digital IO pins manage directional control. Equipped with convenient screw terminals for motor wiring and standard bent header pins for logic inputs, it provides a hassle-free setup for compact mechatronic creations.
Key Features
- Dual L9110S Chip Architecture: Houses dual independent driver circuits to manage two separate DC motors or a 4-wire 2-phase stepper motor.
- Flexible Voltage Window: Accommodates external supply voltages from 2.5V up to 12V DC.
- Robust Current Delivery: Provides up to 0.8A max operating current per channel without excessive thermal overhead.
- Clear Interface Layout: Includes labeled 6-pin logic control headers (VCC, GND, AIA, AIB, BIA, BIB) and 4-pin green screw terminals for secure motor output connections.
- Onboard Power Indicator: Integrated LED lights up instantly when VCC and GND supply power is active.
Benefits
- Microcontroller Compatible: Low-voltage logic inputs work natively with battery-powered 3.3V and 5V systems.
- Space-Saving Footprint: Ultra-small dimensions allow deployment inside confined chassis compartments.
- Easy Mechanical Mounting: Built-in structural fixing holes let you screw the board securely onto any robot platform or project box.
Applications
- Miniature Robotics: Ideal motor controller for small two-wheel-drive smart cars, line-followers, and obstacle-avoidance bugs.
- Stepper Motor Projects: Perfect for driving small 4-wire bipolar or unipolar stepper configurations in automated gauges and pan-tilt units.
- Smart Home Automation: Controlling small DC pumps, micro-valves, automated locks, and window shutter toys.
Package Includes
- 1 x SPIDER Automation L9110S DC Stepper Motor Driver Board
