L9110S H-bridge Stepper Motor Dual DC Stepper Motor Driver Controller Board Module
 L9110S L9110 For Arduino

 
There are two L9110S motor control chip onboard
This module can simultaneously drive two DC motors or a 4-wire 2-phase stepper motor
 
Work under low static current
Power supply voltage: DC 2.5V - 12V
Each channel has 800mA continuous current output
Low saturation pressure drop
TTL / CMOS output level compatible, can be connected directly to the CPU
Output built-in clamping diode, apply to the perceptual load
Control and drive integrate in IC
Pin high pressure protection function
Working temperature: 0°C - 80°C
Size: 29 x 21mm(L x W)
 
 
 
1 x L9110S stepper motor driver
