I don’t believe so…when I search, there are several pages for a samC21 that might? We also sell this [https://www.sparkfun.com/products/13262](https://www.sparkfun.com/products/13262)

As for pin functions, here’s a graphical sheet [https://cdn.sparkfun.com/assets/e/0/6/6 … pdated.pdf](https://cdn.sparkfun.com/assets/e/0/6/6/5/SamProRF_Graphical_Datasheet_Updated.pdf) and the official one (our board uses samD21-G) [https://cdn.sparkfun.com/assets/6/3/d/d … asheet.pdf](https://cdn.sparkfun.com/assets/6/3/d/d/2/Atmel-42181-SAM-D21_Datasheet.pdf)
