Prepare the SAM C21 Xplained Pro
...
Make sure that the jumper on the 3-pin header labeled VCC_SEL is set to 3.3 V, as seen in Figure 15. This will select 3.3 V as the supply voltage for the ATSAMC21J18A, peripherals and extension headers, which is important as we will power the mote from the latter.

Figure 26: Mote connected to the SAM C21 Xplained Pro.
The Xplained Pro has three extension headers (EXT1, EXT2, EXT3) with pins as listed in Table 17: Connect the mote to one of the headers, as per the mapping in Table 28. In Figure 26 you can see the mote connected to EXT1, but it does not matter which one you use: The pins for UART RX/TX on all three headers are connected to the same pins on the SAM C21.
