Figure 9: UART Switch

Slide this switch to the left side to establish communication between HC06U and the USB interface. Slide

this switch to the right side to establish communication between HC06U and external MCU UART. CN3

and CN5 test points on both sides of the switch correspond to UART and power supply pin of MCU and

USB interface respectively, which will not be described in next chapter about test points.
