Description
USB-to-Serial Adapter Carrier Board, CP2102N
This USB-to-serial adapter is a breakout board for the Silicon Labs CP2102N USBXpress USB-to-UART bridge, and it is a great solution for connecting microcontroller projects and other logic-level serial devices to a personal computer. This board offers several options for accessing the data, control, and GPIO pins on the CP2102N, all of which are made available on a 0.1″ spacing.
This board uses 3.3 V signal levels by default, but the signal pins can tolerate higher voltages, allowing the adapter to be used with 5 V systems that see 3.3 V as a logic high. The green LED on the SUSPEND line indicates an active USB connection when lit.
The adapter looks like a standard virtual serial port (COM port) to the computer’s operating system, which means it can be used with any software designed to work with a serial port (even a legacy RS-232 port). The CP2102N is a full-speed USB 2.0 device and allows baud rates of up to 3 Mbps. Drivers are available from Silicon Labs for Windows XP, Windows Vista, Windows 7, Windows 8, Windows 10, Linux, and Mac OS X
