Description
L9110S Dual H-Bridge Motor Driver Module
This module uses two L9110S motor-control chips. It can drive two DC motors simultaneously or one compatible 4-wire, 2-phase stepper motor. Its TTL/CMOS-compatible logic inputs are intended to connect directly to a controller’s logic outputs.
Specifications stated in the listing
- Motor-control ICs: two L9110S chips
- Supply voltage: 2.5–12 V DC
- Maximum output stated: 800 mA per channel
- Logic: TTL/CMOS compatible
- Built-in clamping diodes for inductive loads
- Operating temperature stated: 0–80 °C
- Dimensions: 29 × 21 mm (length × width)
The 800 mA value is the listing’s maximum per-channel rating; actual usable current depends on the board, cooling and operating conditions. Choose a supply within the stated range and suitable for the connected motor. Do not connect a motor directly to controller I/O pins; connect the module’s logic inputs to the controller and observe the module’s supply and wiring labels.
Typical applications
- Two small brushed DC motors
- Compatible 4-wire, 2-phase stepper motors
- Small robots and motorized mechanisms
- Arduino and microcontroller projects
