It should install USB driver before use onPC. After H380 module plugged into the PC, the USB can enumerate seven ports:One 3G Modem/AT port for data transmissionThree ports for sending AT CommandOne port for trace LOG informationTwo ports reserved currently.5.4.2 USB Interface ApplicationReference Design as follow:Figure 5- 6 USB Interface Reference DesignThe capacitor of TVS(T101 and T102) must be less than 1pF. VUSB power supply has beenconnected internal, so the VBUS pin of HOST can float.USB_D+ and USB_D- are high speed differentialserial signals, the highest transmit speed is up to 480 Mbps.PCB Layout note:USB_D+ and USB_D- signals trace same length, parallel, as short as possible.USB_D+ and USB_D- should be isolated by Ground in same and adjacent layer. It is better for USBperformance when adding more GND VIA.USB2.0 signal should trace near the Ground layer of PCB.Impedance control of USB differential signals is 90 ohm.USB signal should keep away from any strong noise signal like power supply etc.

If high level is detected, it means SIM card is inserted.5.5.3 USIM Design NoticeThe SIM interface and signals design is extremely important.There are several design guidelines that must be followed:The signals of the SIM card layout should be away from any possible EMI noise, such as RF antennaand digital switching signals.To ensure signal integrity, the length between SIM interface signals and module should not exceed100 mmTo avoid crosstalk between USIM_CLK and USIM_IO, it is recommended to route them separately onthe application board, and preferably isolated by Ground layer.
H380 M.2 Series Module Hardware User Manual page 29 of 41The SIM card signals should be protected by ESD component(low capacitance capacitor, such asZener diode). The recommended part no of ESD component is AVR-M1005C080MTAAB (TDK). ESDcomponent should layout with SIM connector closely.5.5.4 USIM Hot PlugH380 supports the detection function of SIM status,and this function can realize SIM hot plug.5.5.4.1 Hardware ConnectionSIM hot plug function need support of SIM_DETECT signal.When no SIM card, SIM_DETECT is low level; insert SIM, SIM_DETECT is high level.Explanation:1) For normally closed SIM connector circuit, as shown in Figure 5-7.SIM_DETECT connects Pin8 (SW2)of U2, Pin7 (SW1) short GND. When there is no SIM card, SW2 and SW1 short, SW2 is low level. WhenSIM card inserted, SW1 and SW2 disconnect, SIM_DETECT is pulled high.2) For normally open SIM connector circuit, as shown in Figure 5-8. SIM_DETECT connects Pin8 (SW2)of U2, and it also be pulled low by 47K ohms resistor. Pin 7 is pulled high by 4.7K ohms resistor. When noSIM card, SW2 and SW1 disconnect, SW2 is low. After SIM inserted, SW2 and SW1 short, SIM_DETECTis pulled high.5.5.4.2 Software Configuration“+MSMPD” AT command control SIM card hot plug function on/off.AT+MSMPD=0, SIM card hot plug deactivated. Module does not detect SIM_DETECT signal.AT+MSMPD=1, SIM card hot plug activated. Module support SIM hot plug by SIM_DETECT pinsignal status.SIM_DETECT High level, SIM card is present, module registers the network automatically.SIM_DETECT Low level, SIM card is absent, module drops out the network.Note: The “+MSMPD” default value is “1”. SIM_DETECT is only used for SIM card hot plug detection,Module don’t detect SIM_DETECT signal at the first startup(it means the module will read SIM card dataand register network at the first startup, no matter pin SIM_DETECT is high or low).5.6 Digital AudioH380 M.2 supports digital audio I2S interface.

The radiation power ofan antenna is always lower than the input power due to the following factors: return loss, material loss,
H380 M.2 Series Module Hardware User Manual page 38 of 41and coupling loss.Efficiency of the master antenna > 40% (–4dB)(2) S11 or VSWRS11 (return loss) indicates the degree to which the input impedance of an antenna matches the referenceimpedance (50 ohm). S11 shows the resonance feature and impedance bandwidth of an antenna. Voltagestanding wave ratio (VSWR) is another expression of S11. S11 relates to the antenna efficiency. S11 canbe measured by vector analyzer.S11 of the master antenna < –10 dB(3) PolarizationThe polarization of an antenna is the orientation of the electric field vector that rotates with time in thedirection of maximum radiation.Linear polarization is recommended: it would be better if the polarization direction of diversity antenna isdifferent from main antenna.(4) Radiation PatternRadiation pattern refers to the directional dependence of the strength of radio waves from the antenna orother source.The radiation pattern of half wave dipole antennas is the best for wireless terminals. If it is built-in antenna,PIFA antenna is recommended:Antenna area (H x W x L): 6mm x 10mm x 100mm. PIFA or IFA antenna is recommended.Radiation Pattern: Omni-directional(5) Gain and DirectivityThe directivity of the antenna is the electromagnetic field strength of the electromagnetic wave in eachdirection. An antenna's power gain is a key performance Figure which combines the antenna’s directivityand electrical efficiency.Recommended antenna gain ≤ 2.5dBi(6) InterferenceBesides the antenna performance, the interference on the PCB board also affects the radio performance(especially the TIS) of the module. To guarantee high performance of the module, the interferencesources on the user board must be properly controlled. On the PCB board, there are various interferencesources that can affect the module, such as the speaker, LCD, CPU, FPC trace and audio circuits, thepower supply should be far away from antenna, notice isolation, shield and filtering processing issues.(7) TRP/TISTRP (Total Radiated Power):
