Pololu USB-to-Serial Adapter

Note: This product is not recommended for new designs (NRND) based on Silicon Labs designating the CP2102 as NRND. Please see the CP2102N USB-to-Serial Adapter Carrier for a similar, newer adapter with a USB Micro-B connector.

The Pololu USB-to-serial adapter is great for connecting microcontroller projects to a personal computer. The adapter uses 3.3 V signal levels so you can connect it directly to any microcontroller running at up to 5 V without the hassle of an RS-232-to-TTL level converter. The tiny unit is only 1.0″ x 0.65″ including its mini-B connector, and the simple layout of the ground, transmit, and receive lines allows for easy mounting that takes up as little as four breadboard rows.
