Side A: Dual USB-C Ports
Side B: Device Connection
How It Works
LumeLink's innovative three-port design offers a safer and more durable approach to UART debugging for USB-C devices:
Port Configuration
- Side A (2 ports): One port passes through completely, while the second connects to the UART chip to read SBU1/SBU2 pins
- Side B (1 port): Connects to your USB-C device using a 16-pin or higher USB-C cable
LumeLink's all-female port design ensures that only the replaceable cables are at risk of damage, protecting your investment and providing a more reliable debugging experience.
How It Works
Side A: Dual USB-C Ports
One complete passthrough port, one for capturing UART data via SBU pins
Side B: Single USB-C Port
Connects to your device to read UART data from SBU1/SBU2 pins
