Disc Pump Drive Electronics and Accessories

Getting Started?

We recommend that customers start with the Piezoelectric Disc Pump Evaluation Kit, which enables rapid evaluation of the pump, without any upfront development effort. The kit implements a range of commonly-used functions, including closed-loop pressure/vacuum control, and contains everything necessary to start testing: two pumps of your choice, drive electronics with an integrated pressure sensor, power supply, PC application for configuration, control and data logging, together with tubing, connectors and filters

General Purpose Drive PCB

Integration

The General Purpose Drive PCB is designed to be mounted on a set of 0.5” (1.27 mm) pitch single inline headers. No additional mechanical restraint is required. Dimensions for the General Purpose Drive PCB are shown in millimeters.

Breakout PCB

The General Purpose Drive PCB can be mounted on the Breakout PCB, which presents the PCB electrical interface on two 0.1” (2.54 mm) single inline headers, suitable for integration with 0.1” prototype board, enabling rapid prototyping and testing at the start of the development process.

Part Number: UACX0500100E

Our GitHub code snippet library provides examples of how to control the Disc Pump Evaluation Kit independently of the Disc Pump Control App. The initial examples provided cover a range of functions, including turning the pump on and off, setting drive power, closed loop control of pressure and reading back and plotting data.

The code snippet library, which is hosted on GitHub, is intended to support customers after their initial evaluation of our pump technology, as they move on to developing prototypes and products. We welcome suggestions for how we can improve and build upon this repository; please feel free to share your ideas, feature requests and any bugs you identify with us.
