The CP2102 USB to UART TTL is a small control bridge for upgrading RS-232 designs to USB, with minimal components and PCB space, offering maximum performance with full USB 2.0 functionality. The board features a USB transceiver, an oscillator, 1KB programmable EEPROM, and asynchronous serial data with full modem control signals. All of this is packed into a small 42x15mm package, without requiring external USB components or power sources for its operation.

The device is powered via USB and uses intelligent software that includes all RS-232 control and synchronization signals. This means you don’t have to worry about software upgrades; simply connect the device directly to a USB port on your computer, it appears as a virtual COM port, and you can upgrade your designs from RS-232 to USB. Basic driver installation is required to prepare the device, after which it can use various standard Baud rates between 300bps and 1Mbits for serial communications. This eliminates the need for RS232 to TTL converters such as the MAX232, ensuring a more convenient and accessible method for upgrading RS-232 designs, especially for laptops without serial ports.
