Design a Custom BoardAbout This Component
Single-chip USB-to-UART bridge controller implementing USB 2.0 full-speed (12 Mbps) with integrated transceiver, clock, and voltage regulator. Supports baud rates from 300 bps to 2 Mbps with full modem handshaking signals, 576-byte buffers, and four GPIO pins. Includes 1024-byte programmable ROM for device customization and works with virtual COM port drivers across Windows, macOS, and Linux for legacy serial-to-USB conversion 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.
