The IQS572-B000 is a firmware upgrade from the IQS572-A000. The IQS572 is a projected capacitive touch and proximity trackpad/touchscreen controller implementation on the IQS5XX platform. The IQS572 features best in class sensitivity, signal-to-noise ratio and automatic tuning of electrodes. Low power proximity detection allows extreme low power operation. The IQS572-BL contains a bootloader to enable loading of the B000 firmware. IQS572-A000 devices can be upgraded to the IQS572-B000 firmware via the bootloader.

Let us help you implement your IQS572-B000.
We’ve done it before.
If you don’t believe us test it yourself.

Includes 1x IQS572 Shield board. Plug Shield board into Arduino Uno/ST Nucleo to evaluate trackpad performance and outputs. Alternatively, connect with CT210/A directly to PC GUI.

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