What is CP2102?
Table of Contents
CP2102 chip from SiLabs is a single chip USB to UART bridge IC. It requires minimal external components. CP2102 can be used to migrate legacy serial port based devices to USB. Hobbyists can use it as a powerful tool to make all kinds of PC interfaced projects.
What is a CP210x driver?

The CP210x USB to UART Bridge Virtual COM Port (VCP) drivers are required for device operation as a Virtual COM Port to facilitate host communication with CP210x products. These devices can also interface to a host using the direct access driver.
What is CH340G?
The CH340G USB to Serial (TTL) Module&Adapter is a small USB to TTL serial tool, which uses the CH340G chip. You can use it to connect a serial device to your PC via USB port. Features: Compatible with 32-bit & 64-bit Windows, Mac OS 8 to OS X, Linux and Android.
What is UART module?
The Universal Asynchronous Receiver Transmitter (UART) module is the basic serial I/O module available in the dsPIC30F device family. The UART is a full-duplex asynchronous system that can communicate with peripheral devices, such as personal computers, RS-232, and RS-485 interfaces.

What is a serial enumerator?
The function of the serial enumerator is to detect a Plug-and-Play enabled device (such as a serial mouse or serial modem) that is attached to the USB serial port.
What is UART bridge?
USB to UART converters or bridges present themselves as a serial port to your computer and send serial data over a couple of wires. They can be used to make a serial connection to another device.
What is included in the CP2102 evaluation kit?
The CP2102 Evaluation Kit includes an evaluation board with a CP2102 device pre-installed for evaluation and pre- liminary software development. Numerous input/output (I/O) connections are provided to facilitate prototyping using the evaluation board. Refer to Figure3 for the locations of the various I/O connectors.
What is the cp2102n device?
The CP2102N devices are highly integrated USB-to-UART bridge controllers in packages as small as 3 mm x 3 mm. These devices include a USB 2.0 full-speed function controller with integrated USB transceiver and clock, voltage regulator and Universal Asynchronous Receiver/Transmitter (UART) reducing BOM costs and simplifying the design.
What drivers do I need for the cp2102n mini Ek?
Silicon Labs’ direct access driver package can also be used with the CP2102N Mini EK. The included quick-start card provides information on each header and test point. The CP210x USB to UART Bridge Virtual COM Port (VCP) drivers are required for device operation as a Virtual COM Port to facilitate host communication with CP210x products.
What is a J3 connector on the CP2102?
A Universal Serial Bus (USB) connector (J3) is provided to facilitate connections to the USB interface on the CP2102. See Table1 for the USB pin definitions. Table 1.
