[USB-101]FT2232H Evaluation Board

Last Updated: Wednesday, 14 January 2015

USB-101 FT2232H Evaluation Board

USB-101 is an evaluation board of FTDI's FT2232H. FT2232H supports USB 2.0 Hi-Speed(480Mbps).
You can utilize this board for FT2232H performance estimating, preproduction prototypes, USB communication interfaces for your application and more.

Difference between this USB-101 and USB-103 is number of channels that be connect to user interface.
In USB-101, you can use both channel A and channel B.
In USB-103, you can use channel A and a part of channel B (Tx and Rx).
