Motor Driver (L9110S)

Motor Driver (L9110S)

SKU:AX22-0032

Need to spin one DC motor forward, reverse, coast, or brake without burning GPIOs? This AX22 board does it neatly. A robust L9110S H-bridge sits on a 22 × 22 mm PCB and is wired for one motor only, handling up to 800 mA continuous (2.5 A peak) from 2.5 – 9 V. Two active-high control pins (IN1, IN2) give simple direction and PWM speed control. Power can come from the AX22 backplane’s power rail or a separate external VExt Input, just move a solder jumper to select. Snap it into an AX22 backplane and drive wheels, sliders, or pumps in minutes with Arduino IDE, MicroPython, or MicroBlocks.
