* If you want to use the MIC_BIAS of module, connect VBAT(31) to 3.3V.

(MIC_BIAS Voltage range: 1.7 ~ 3.3V) But we don’t recommend using the Internal MIC_BIAS because of noise issue.

* VCHG(35) pin can’t be used.

4. UART Interface

This is a standard UART interface for communicating with other serial devices. MD-5XR UART interface provides a simple mechanism for communicating with other serial devices using the RS232 protocol. UART configuration parameters, such as baud rate and packet format, are set using MD-5XR firmware.

4.1 UART Bypass Mode

To apply the UART bypass mode, a BCCMD command is issued to MD-5XR. Upon this issue, it switches the bypass to PIO[7:4] as shown in figure. When the bypass mode has been invoked, MD-5XR enters the Deep Sleep state indefinitely.
