For more details of AT commands about UART, please refer to document [1] and [22].
DTR pin can be used to wake MODULE from sleep. When MODULE enters sleep mode, pulling down DTR
can wake MODULE.
3.4USB Interface
The MODULE contains a USB interface compliant with the USB2.0 specification as a peripheral, but the
USB charging function is not supported.
MODULE can be used as a USB device. MODULE supports the USB suspend and resume mechanism
which can reduce power consumption. If there is no data transmission on the USB bus, MODULE will enter
suspend mode automatically, and will be resumed by some events such as voice call, receiving SMS, etc.
Figure 19: USB reference circuit
Because of the high bit rate on USB bus, more attention should be paid to the influence of the junction
capacitance of the ESD component on USB data lines. Typically, the capacitance should be less than 1pF. It
is recommended to use an ESD protection component such as ESD9L5.0ST5G provided by On
Semiconductor (www.onsemi.com ).
D3 is suggested to select the diode with anti-ESD and voltage surge function, or user could add a TVS for
surge clamping. The recommend TVS please refer to table 7.
