EMW3072
6. Reference Circuit
The EMW3072 power supply reference circuit is shown in Figure 10, Figure 10 USB serial port reference circuit
and Figure 11 external interface reference design for user reference.
Figure 10 Power Reference Circuit
Figure 11 USB to UART Reference Circuit
Figure 12 EMW3072 External Interface Reference Design
EMW3072 UART is 3.3V UART. If the UART of the chip is 5V, the user needs to convert 5V U ART to 3.3V UART
to communicate with EMW3072 UART. The 5V-3.3V UART conversion circuit refers to the circuit shown in
Figure 13.
