SunFounder 3in1 Kit
• It is a submersible pump and should be used that way. It tends to heat too much that there’s a risk of
overheating if you turn it on unsubmerged.
Example
• 1.4 Pumping (Basic Project)
• 6. Plant Monitor (IoT Project)
1.16 L9110 Motor Driver Module
The L9110 motor driver module is adept at driving two motors in tandem. It houses a pair of independent L9110S
driver chips, each channel boasting a steady current output of up to 800mA.
Spanning a voltage range from 2.5V to 12V, the module comfortably pairs with both 3.3V and 5V microcontrollers.
Serving as a streamlined solution, the L9110 motor driver module facilitates motor control across a spectrum of ap-
plications. Thanks to its dual-channel architecture, it enables the independent orchestration of two motors—ideal for
projects where dual motor operations are paramount.
Given its potent continuous current output, this module confidently powers motors from the petite to the moderately
sized, paving the way for diverse robotic, automation, and motor-centric endeavors. Its expansive voltage range further
injects adaptability, aligning with varied power supply setups.
Designed with user-friendliness in mind, the module offers intuitive input and output terminals, simplifying connections
to microcontrollers or akin control devices. Plus, it doesn’t skimp on safety—integrated overcurrent and overtempera-
ture safeguards bolster the trustworthiness and security of motor operations.
• B-1A & B-1B: Input pins for controlling the spinning direction of Motor B.
• A-1A & A-1B: Input pins for controlling the spinning direction of Motor A.
• 0A & OB(A): Output pins of Motor A.
