The microUSB Programming Adaptor (uUSB-PA5) 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 and is based on the FTDI FT232RQ USB to Serial Bridge IC from FTDI Chip.
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 is ideal for prototype or production.
RX and TX signals are both 3.3V and 5V tolerant.
The uUSB-PA5 was designed in 2012 to be the programming adaptor of choice going forward for new products. While a large range of 4D Systems modules are compatible with this programming adaptor, some are not, for mechanical reasons.
The following is a small list is of known modules that are not compatible with the uUSB-PA5.
Please use the 4D Programming cable instead.
