5.2 Revision 2
Revision 2 of PROTO1 Xplained Pro is the initial released version.
PROTO1 Xplained Pro boards with a serial number that ends with a number lower than 19048 may have a wrong revision programmed into the Xplained Pro ID chip. This will only affect the information displayed by the Atmel Kits extension in Atmel Studio. It will not affect the operation of the board.
