1 Port USB to Serial RS232 Adapter - Prolific PL-2303 - USB to DB9 Serial Adapter Cable - RS232 Serial Converter (ICUSB232V2) Sabrent USB 2.0 to Serial (9-Pin) DB-9 RS-232 Converter Cable Additional resources, including application notes referenced by the datasheet, can also be found on the CP21xx product page of the Silicon Labs website.Tripp Lite Keyspan High-Speed USB to Serial Adapter For advanced users interested in these features, we recommend careful reading of the CP2104 datasheet (224k pdf). You do not need to be familiar with details of the CP2104 to use this board as a basic USB-to-serial adapter, but the CP2104 also has specialized features including four general-purpose I/O (GPIO) pins and the ability to be customized via its one-time programmable ROM.

This schematic is also available as a downloadable PDF (188k pdf). You can then solder a thin wire to the exposed via labeled “VIO” and connect it to a separate voltage supply (as low as 1.8 V). If you want to use a lower logic voltage, you can disconnect VIO from VDD by cutting the thin trace between the two pads of the surface-mount jumper shown to the right. This carrier board connects the VIO pin of the CP2104 to VDD by default, setting its logic voltage level to the 3.45 V provided by the IC’s built-in voltage regulator. You can also solder wires directly to the pads for the smallest installation. The carrier board ships with a 1×25 straight male header strip, a 1×6 right-angle male header strip, and a 1×6 right-angle female header as shown below. As a result, this CP2104 adapter board can be used as a drop-in replacement for an FTDI cable in many applications, such as programming Arduino-compatible boards.ĬP2104 USB-to-serial adapter carrier in a breadboard with included 0.1″ male headers installed.ĬP2104 USB-to-serial adapter carrier with included 6-pin 0.1″ right-angle female header installed. This gives access to six signals (RTS, RX, TX, VBUS, CTS, and GND) that are commonly found on FTDI cables and other similar USB-to-serial adapters. This allows any pin to be accessed easily while the adapter is plugged into a solderless breadboard, as shown in the left picture below.Īlternatively, a 1×6 header can be soldered to the end of the board, as shown in the right picture below.

Drivers are available from Silicon Labs for Windows XP, Windows Vista, Windows 7, Windows 8, Windows 10, Linux, and Mac OS X. The CP2104 is a full-speed USB 2.0 device and allows baud rates of up to 2 Mbps.

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 green LED on the SUSPEND line indicates an active USB connection when lit.
This board uses 3.45 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 3.45 V as a logic high. It offers several options for accessing the data, control, and GPIO pins on the CP2104, all of which are made available on a 0.1″ spacing. The tiny unit measures only 0.6″ × 0.95″ including its Micro-USB connector.
This USB-to-serial adapter is a breakout board for the Silicon Labs CP2104 USB-to-UART bridge, and it is a great solution for connecting microcontroller projects and other logic-level serial devices to a personal computer. OverviewĬP2104 USB-to-serial adapter carrier, bottom view with dimensions. Its lower-priced successor, the CP2102N USB-to-Serial Adapter Carrier can be used as a drop-in replacement in most applications, and it offers a few improvements including support for higher baud rates (up to 3 Mbps) and a re-programmable configuration ROM. Note: This product is not recommended for new designs (NRND) based on Silicon Labs designating the CP2104 as NRND.
