Frequently asked about this product
What does the 4-Channel 3 A DC Motor Driver (RZ7889) need for power and control?
The 4-Channel 3 A DC Motor Driver (RZ7889) is driven from the mainboard through a standard header or terminal connection; motor/logic supply (5-12 V depending on load) goes in through the dedicated power input, and the logic side runs at 3.3-5 V. LED indicators show channel status, and the module is protected against reverse connection.
What voltage does the 4-Channel 3 A DC Motor Driver (RZ7889) run on?
The 4-Channel 3 A DC Motor Driver (RZ7889) has separate logic and load supplies: the logic side takes 3.3-5 V from the controller, while motors or high-current outputs are fed from their own 5-12 V supply through the dedicated power terminal. Never power the load side from the controller’s 5 V pin.
What projects is the 4-Channel 3 A DC Motor Driver (RZ7889) good for?
The 4-Channel 3 A DC Motor Driver (RZ7889) is built for STEM and robotics education: classroom demonstrations, science-fair projects, robotics club builds and competition robots. It pairs with the rest of our module range — same connectors, same voltage, same toolchain — so students move from first circuit to competition robot without changing platforms.
What certification do the robotics and electronics products carry?
Controller boards, sensors and modules ship with CE marking and RoHS-compliant components, and the range is designed for classroom use under teacher supervision. Product-specific test reports and declarations of conformity are available for distributors on request.
What is the minimum order quantity, and can I get a sample first?
These are standard catalogue lines with stable production, so minimums are low and lead times are short. Samples ship within about a week and are normally credited against a first order. Mixed-SKU cartons are accepted for evaluation orders.
