The IQS266 ProxSense® IC is a 2×3 projected capacitive trackpad designed for low power mobile applications. This trackpad is perfect to implement on a single sided ITO touch screen for wearables. A self-capacitive channel is used for wake-up which keeps the power consumption in low-power less than 5 uA. Other features include automatic tuning for sense electrodes, internal reference capacitor and internal regulator to reduce total system cost.


    • Capacitive sensing:

Let us help you implement your IQS266.
We’ve done it before.
If you don’t believe us test it yourself.

Includes 1x IQS266 Shield board and 1x IQS266 FPC Trackpad PCB
Plug Shield board and Stamp module into Arduino Uno/ST Nucleo to evaluate functions. Alternatively, connect Shield board/FPC Trackpad PCB with CT210/A directly to PC GUI. 

NOTE: Arduino Uno/ST Nucleo not included. CT210/A sold separately.
