uUSB-PA5-II

The microUSB Programming Adaptor uUSB-PA5-II is a USB to Serial-TTL UART bridge 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. The uUSB-PA5-II is based on the SiLabs CP2104 USB to UART Bridge IC from Silicon Labs. The predecessor of the uUSB-PA5-II was the uUSB-PA5, this featured a FTDI FT232RQ USB to UART Bridge IC, however this is no longer produced by 4D Systems. Both models are still however featured in the Datasheet.

It provides the user with multi baud rate serial data up to 3M baud rate, and access to additional signals such as flow control in a convenient 10 pin 2.54mm (0.1″) pitch Dual-In-Line package.

The main 5 pin interface is a standard 2.54mm (0.1″) pitch female header, designed to connect directly to a majority of the 4D Systems modules.

The uUSB-PA5-II is ideal for prototype or production.

RX and TX signals are both 3.3V and 5V tolerant.

NOTE: The uUSB-PA5-II requires a standard USB mini cable which is not included.

NOTE: Illustrations present the uUSB-PA5 instead of the uUSB-PA5-II, however only the uUSB-PA5-II is now available.

How to determine which COM port is allocated to the uUSB-PA5-II:

• Go to Control panel and double click on the “System” Icon and the “System Properties” window will open up.
• Click on the “Hardware” window tab and then the “Device Manager” button.
• Go down the list and expand the “Ports (COM & LPT)” devices.
• There you will see the COM port that has been allocated for the μUSB-PA5/PA5-II.
• Take note of the COM port number (e.g. COM4) as you will need this when configuring the COM port for applications that need to communicate with the uUSB-PA5-II such as the 4D-Workshop IDE.
