Peristaltic Liquid Pump with Silicone Tubing - 12V DC Power

Peristaltic DC pump that moves fluid through silicone tubing without the motor contacting the liquid, suitable for food, drink, or sterile applications. Speed is controllable via PWM; reversing polarity reverses flow direction.

Motor lead A
One of the two DC pump motor supply leads. The Adafruit product page identifies this as a 12V DC peristaltic liquid pump and states it can be driven by a power transistor or motor driver; reversing polarity moves fluid the other direction.
Type · PowerVoltage · 12V DC pump drive, per Adafruit product page
Motor lead B
The second DC pump motor supply lead. Use with the other lead as the two-wire motor drive connection; polarity determines pump direction according to the Adafruit product page.
Type · PowerVoltage · 12V DC pump drive, per Adafruit product page
Tubing inletoutlet
Silicone tubing fluid path supplied with the peristaltic pump. The product page notes the installed silicone tubing and two attached 1/2 metre pieces; fluid direction depends on motor drive polarity.
