+!!! note
+    Ref. [Quentin_2020](https://fabacademy.org/2020/labs/ulb/students/quentin-bolsee/projects/samd11c_uart-updi/)  
+     The UART connector is directly wired to the RX and TX of the serial 0 on the D11C. On the RX pin, the 1.2 kΩ resistor offers some protection in case the other device is talking in 5V serial. The internal protection of the D11C saturates inputs to VDD+0.6V, but can only accept a small injection current. According to the datasheet, we should be safe in this case. Let’s compute the current when RX is at 5V:  
+
+    ![](./images/week06/rest_equipment/quentin_formula.png){width=300}  
+
+     which is below the reported limit. When enabling the UPDI mode with the jumper, the RX and TX pins are simple shorted together, along with a 4.7 kΩresistor. This resistor limits the current to the TX pin, which is low impedance as it is configured as an output on the D11C. The value of this resistor is not critical, you can also use 5 kΩ.
