@@ -10,6 +10,12 @@ The SAM V71 Xplained Ultra evaluation kit is a development platform to
 evaluate the Atmel SAM V71 series microcontrollers. The current version
 allows to use both IC variations ATSAMV71Q21A(B).
 
+There are two additional variations of this board, sam_v70_xult and
+sam_v70b_xult. While these are not actually manufactured variations, they exist
+to test the SAM V70 support. These boards are configured with an ATSAMV70Q20(b)
+processor and are functionally identical to the SAM V71 versions, minus
+Ethernet.
