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.
Can I have clarification on the "0 Ohm" resistor needed for the 1.8v test and Arduino Uno configuration. Can you actually buy a surface mount 0 Ohm resistor? Would a wire loop work just as well? Any tips for soldering that using a standard iron?
I'm still not happy that I understand the thresholds and sensitivity settings well enough for my planned gloved tests but hopefully will find some documentation or just experiment with the settings.
It really depends where you are. I'm not sure if the kits are shipping from Cypress (which I think is in Virginia, USA), Element 14 Newark (also in the USA), or Element 14 Farnell (which is in the UK). Basically, if you're in Asia, Australia, or possibly more distant parts of North or South America, it'll probably take a little while to get to you.

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…
