USB-to-Serial Bridge – µUSB-PA5-II

The microUSB Programming Adapter (μUSB-PA5-II) is a USB to Serial-TTL UART bridge converter which is very small and easy to use. It uses a mini-B type USB connector to connect to your PC andis based on the SiLabs CP2104 USB to Serial Bridge IC from Silicon Labs. Each adapter will give you multi-baud rate serial data up to 3M baud rate and access to additional signals such as flow control. 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.

RX and TX signals are both 3.3V and 5V tolerant. This module replaces the variety of existing 4D serial bridges for the LCD kits that we carry. While a large range of 4D Systems modules are compatible with this programming adapter, some are not, for mechanical reasons.

Note: This is a revision of the USB-to-Serial Bridge (μUSB-PA5). It is based on the SiLabs CP2104 USB to Serial Bridge IC from Silicon Labs as oppposed to its predecessor which was based on the FTDI FT232RQ USB to Serial Bridge IC from FTDI Chip. From the perspective of programming 4D Systems modules, both the uUSB-PA5 and uUSB-PA5-II operate in the same way.
