Breakout Board for CP2102 mini USB to Serial

Replacement:DEV-11814. This item has been discontinued and we are no longer carrying it. This page is for reference only.

The μUSB-MB5 is a USB to serial (TTL) converter which is simple, cost effective, very small and easy to use. It uses a mini-B type USB connector to connect to your PC and is based on the CP2102 Bridge from Silicon Labs. It provides the user with multi baud rate serial data and access to flow control signals in a convenient 10 pin 0.1” pitch Dual-In-Line package.

The μUSB-MB5 makes an easy USB-Serial interface, so you can easily create USB to RS-232 converters. In any application, make sure the TX and RX lines from the μUSB are crossed over to the attached peripheral. That is, the TX from the μUSB connects to the RX of the target and the RX from the μUSB connects to the TX of the target device.

Please note: The TX and RX signal levels are between 0.0 Volts and 3.3 Volts.
