How can you tell by looking at the board if your Olimexino-32U4 is Rev.A or Rev.A3? The difference is that D14 and D17 have switched roles. On Rev.A D17 goes to UEXT pin 7 i.e. MISO, but on Rev.A3 to RXLED.

I have Rev.A3, but I determined that by blinking RXLED.

We are currently manufacturing hardware revision B of OLIMEXINO-32u4. I would update the files as soon as possible.

What is printed on the top of the board right from the lion logo? It is says revision "A" and you purchased the board in or after 2014, then it is hardware revision A3.

It seems you can't easily see a difference between the boards for Rev.A and Rev.A3.

What is the difference between Rev.A3 and Rev.B?

This file is not updated with Rev.B: https://www.olimex.com/Products/Duino/AVR/OLIMEXINO-32U4/resources/OLIMEXINO-32U4.pdf
