CapSense® MBR3 is Cypress’s solution for quickly and easily replacing mechanical buttons with sleek and reliable capacitive-sensing user interfaces. The CapSense MBR3 family is the world’s easiest capacitive-sensing solution that allows you to design with the click of a mouse using our GUI-based software tool, EZ-Click™.
CapSense MBR3 combines the best of CapSense features including SmartSense™ Auto-Tuning, robust water tolerance and best-in-class proximity sensing while delivering reliable performance under all conditions. The CapSense MBR3 family comes in four small packages that are suited for various capacitive-sensing designs.
Features
Easiest-to-Design
CapSense MBR3 requires no firmware development – these devices are register configurable by any I2C host, like PSoC, Arduino or the Raspberry Pi
EZ-Click™ GUI-based software tool configures devices without the need to write any code
SmartSense Auto-Tuning
A CapSense algorithm that continuously compensates for system, manufacturing and environmental changes
Eliminates the need for manual tuning during all product design phases
Robust Water Tolerance
CapSense MBR3 works under water droplets, rain, mist and other liquids
Ensures no false touches even under streaming water
Industry's Best Capacitive Proximity Sensing
Achieve up to 30cm in proximity sensing distance
Implement advanced features like wake-on-approach to support ultra-low power applications
Reliable Performance
Advanced sensing algorithms ensure reliable performance even in noisy environments
Implement designs with Signal-to-Noise Ratio (SNR) of > 100:1
As a bonus to our testers, each Capsense MBR3 Evaluation Kit will be shipped with a Raspberry Pi so the full potential of this product can be further explored.
Terms & Conditions
Testers will be selected on the basis of quality of applications: we expect a full and complete description of why you want to test this particular product.
Testers are required to produce a full, comprehensive and well thought out review within 2 months of receipt of the product.
Failure to provide this review within the above timescale will result in the enrolee being excluded from future Road Tests.
Finally got I2C working so that I could post a full review. Check it out here. I will be adding a few pictures and so forth, but my conclusions are all written down.
An idea I just saw on the adafruit website is using conductive tape to make up your capacitive sensors. Perhaps an alternative to the evaluation kit would be a breakout board and a selection of different conductive tape shapes.
The demos worked out fine. It's really simple to use. I do not have the code to interface with RPi but I found some code on the element14 blog and created a repository on GITHUB. Will be working to connect it with an arduino. I am also in the process of designing a PCB based on an Arduino and the Capsense. Anyone know where I can get sample devices for a prototype?

Hi DAB,
As such, the CapSense MBR3 products are not designed to detect water droplets. In fact, it has available features to ignore water droplets and ensure the buttons still work in the presence of moisture…
