Design a Custom BoardAbout This Component
Single-chip USB 2.0 full-speed to UART bridge controller integrating transceiver, oscillator, and voltage regulator. Supports data transfer rates up to 3 Mbaud with integrated 512-byte RX/TX buffers and 960-byte configuration memory. Requires no external USB components, firmware development, or crystal; configured via GUI tool. Ideal for legacy serial-to-USB conversion, POS terminals, dongles, and embedded connectivity applications.
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.
