Frequently asked questions
Can I run this pump at 5 V?
The listing gives a usable range of 8 to 18 V with a rated voltage of 12 V, so 5 V is outside the stated range and the pump may not run reliably. Use a 12 V supply, or any voltage within 8 to 18 V.
Can a microcontroller drive this pump directly?
No. At around 1 A, the pump needs its own 12 V supply and a transistor or MOSFET driver controlled by the microcontroller, with a common ground. Driving it directly from an I/O pin can damage the board.
