Design a Custom BoardAbout This Component
Single-chip Ethernet transceiver supporting 10BASE-T and 100BASE-TX with RMII v1.2 interface. Features auto-negotiation, auto MDI/MDI-X detection, on-chip termination resistors, LinkMD cable diagnostics, and programmable LED outputs. Operates from 3.3V single supply with integrated 1.2V core regulator and flexible I/O voltage options.
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.
