M-G32EV031 Data Sheet USB Evaluation Cable Interface / Breakout Board for EPSON IMU OVERVIEW This USB Evaluation Cable Interface/Breakout Board is designed to convert the 1mm pitch connector of the Epson IMU to a 2.54mm pitch connector. This USB Evaluation Cable Interface/Breakout Board enables a PC to control the Epson IMU via USB interface when used with the USB Evaluation Cable:M-C30EV041. The USB evaluation tools simplify the initial evaluation and rapid testing of the Epson IMU products.
