Design a Custom BoardAbout This Component
Capacitive touch sensing controller supporting up to 16 buttons, 2 sliders, and proximity sensors in a 24-QFN package. Features advanced CSD PLUS algorithm with >100:1 signal-to-noise ratio and SmartSense auto-tuning for robust performance in noisy environments. Ideal for capacitive touch interfaces with minimal firmware development required.
Package: QFN-24 (4×4mm) · 24 pins
Why does this need a breakout?
This 0.5mm pitch QFN is nearly impossible to hand solder and entirely incompatible with breadboards due to hidden pads beneath the package. A breakout board provides accessible headers and pre-soldered connections, letting you prototype with InvenSense motion sensors via I2C or SPI without specialized SMD equipment or rework skills.
