Peristaltic DC pump (5–6V) that moves fluid through silicone tubing without motor contact with the liquid, suitable for food, drink, or sterile applications. Speed is controllable via PWM; reversing polarity reverses flow direction.
One of the two DC motor leads for the peristaltic pump motor. Adafruit describes the pump as a geared-down DC motor and says reversing the motor connection reverses flow direction.
The other DC motor lead for the peristaltic pump motor. Polarity is reversible for flow direction according to the Adafruit product description.
Fluid path through the silicone tubing. The source describes a peristaltic pump where rollers press the tube and the pump never touches the fluid.
