QUESTION

What is the difference between Rev. 1 and Rev. 1.2 of an MCB1768 or MCB1758 board? Does this hardware revision have any impact on my application?

ANSWER

In revision 1.2 only minor changes have been made that have no influence on examples and applications. Here are the changes in detail:

• Different USB host connector. Because of a mistake in the layout of revision 1, it was necessary to use an upright version of USB host connector. Revision 1.2 has the intended angular version populated.
• Two 0 Ohm resistors R82 and R83 have been added to be able to disconnect the USB interface from pin P1.22 and P1.19 in case these pins are not used for USB host.
• About half of all holes of the port headers were too small by mistake.
