PoUSB 12 is USB to RS232 (UART) adapter. Can be also used as an ARM LPC2000 microcontrolers programmer from NXP (founded by Philips) 


The PoUSB12 is a USB to RS-232 bridge converter which is simple, cost effective, very small and easy to use. It uses a USB-B type 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 USB control signals in a convenient 8 pin 2,54 mm (0.1”) pitch package. The PoUSB12 is ideal for prototype or production.

Typical Applications:
The PoUSB12 makes an easy USB-Serial interface, so you can easily create USB to RS-232 converters, USB to RS-422/RS-485 converters , upgrade legacy RS232 devices, make PDA and cellphone USB interface cables, barcode readers, POS terminals, etc.

In any application, make sure the TX and RX lines from the PoUSB12 are crossed over to the attached peripheral. That is, the TX from the PoUSB12 connects to the RX of the target and the RX from the PoUSB12 connects to the TX of the target device.

Note: the TX and RX signal levels are between 0.0 Volts and 3.3 Volts (5V tolerant).
