TCA8418RTWR Breakout

About This Component

8×3 or 8×2 keypad matrix controller with I2C interface for keyboard scanning and debouncing. Supports up to 24 keys with programmable key codes and interrupt-driven event reporting. Integrates GPIO expander functionality with 10 general-purpose I/O pins. Typical applications include embedded keypads, input panels, and human-machine interface designs.

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.
