The EZO-PMP Kit from Atlas Scientific is a small peristaltic dosing pump and serial controller with all the parts needed to set up a nice home lab environment. The EZO-PMP inside each kit is a small, intelligently designed peristaltic pump that can be used to dispense liquids with a +/-1% accuracy (with calibration). With four modes of operation --- continuous and volumetric dispensing, constant flow rate and dose over time --- this embedded dosing pump kit is perfect for repeatable and reliable measurements.

The pump can simply connect to any TTL UART (such as an FTDI USB bridge or an Arduino RX/TX line) or I2C device. It is equipped with an easy-to-read RGB LED with multiple color codes to help define any situation the EZO-PMP is in. This kit includes everything you need to start using the EZO-PMP. They've even thrown in a tiny graduated cylinder for calibration. Each EXO-PMP runs at 3.3V–-5V for logic and 12V-–24V for the motor and has plenty of example code for multiple formats to get you up and running in no time!

EZO-PMP Kit Product Help and Resources

Core Skill: DIY

Whether it's for assembling a kit, hacking an enclosure, or creating your own parts; the DIY skill is all about knowing how to use tools and the techniques associated with them.


Skill Level: Noob - Basic assembly is required. You may need to provide your own basic tools like a screwdriver, hammer or scissors. Power tools or custom parts are not required. Instructions will be included and easy to follow. Sewing may be required, but only with included patterns.
See all skill levels

Core Skill: Programming

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.

2 Programming

Skill Level: Rookie - You will need a better fundamental understand of what code is, and how it works. You will be using beginner-level software and development tools like Arduino. You will be dealing directly with code, but numerous examples and libraries are available. Sensors or shields will communicate with serial or TTL.

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

2 Electrical Prototyping

Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

    Sparkfun didn't always mark up their products 10x

      Please tell us where you can find this kit for $12.50.

      • Jzerweck / about 6 years ago * / 1

        you would have to order individual parts on ebay but I bet you could get it to 12.50. Probably wouldn't have as nice a controller though, and you would have to put it together yourself.

          You are not just paying for parts, you are paying for the calibration and dosing accuracy as well as the various modes. If all you want is a pump and don't care that much what it actually puts out, buy the $12.50 one. It's the same reason people buy a Rigol or Tektronix scope instead of a DSO nano for less that quarter of the price or why they buy Nippon Chemi-con caps instead of the bargain one hung low special.
