Figure 2: Mote connected to the SAM C21 Xplained Pro.
The Xplained Pro has three extension headers (EXT1, EXT2, EXT3) with pins as listed in Table 1. In Figure 2 you can see the mote connected to EXT1 with the mapping listed in Table 2, but it doesnt matter which one you use: The pins for UART RX/TX are all connected to the same pins on the SAM C21.
| Warning |

Long cables may corrupt the API bus communication: e.g. using an official I/O extender cable for the RPi might not work. |
