7.1 

Revision 10 

Revision 10 of the UC3-A3 Xplained kit is the initially released version. This revision of the kit has the following product 
ID: A09-1053/10. 

7.1.1  Known issues 

7.1.1.1 

Swapped TWI SCL and TWI SDA on header J4 

The TWI lines that are connected to the pins one and two on the header J4 are swapped. Therefore the silkscreen on 
the board is not correct because TWI SCL function is on pin one instead of pin two and TWI SDA function is on pin two 
instead of pin one.
