Note: This product is not recommended for new designs (NRND) based on Silicon Labs designating the CP2104 as NRND. 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.

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. The tiny unit measures only 0.6" × 0.95" including its Micro-USB connector. 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.

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. The green LED on the SUSPEND line indicates an active USB connection when lit.

This product requires a USB A to Micro-B cable (not included) to connect to a computer.

For a similar adapter with a USB Mini-B connector, please see the Pololu USB-to-Serial Adapter.
