3 Interface Application
This chapter describes the hardware interfaces of Mini PCIe EVB, shown as follows:
- Power interface
- USB interface
- Audio interface
- USIM card interface
- UART interface
It also provides information about LEDs, jumper, button and test points to help you use the Mini PCIe
EVB.
3.1. Power Interface
The power supply of Mini PCIe EVB could come from the external input which is connected with power
jack or USB receptacle on the EVB board. The power supply connects to a step-down converter which
can provide the supply voltage (VBAT) required for operating EVB and Mini PCIe module.
Figure 4 shows the simplified power supply schematic, and Figure 5 shows the power interface of Mini
PCIe EVB.

3.2. USB Device Interface
Quectel Mini PCIe module provides a USB 2.0 interface which complies with USB 2.0 standard for
high-speed (480Mbps) functions. It is used for AT command, data transmission, firmware upgrade and
GNSS NMEA output.
Mini PCIe EVB provides a Micro-USB receptacle J302 to connect a host device. The USB data lines
USB_DP and USB_DM are connected directly to the Mini PCIe module. The USB_VBUS line can be used
to supply power for EVB.

3.3. Audio Interface
Quectel Mini PCIe module provides one digital audio interface (PCM). Mini PCIe EVB is equipped with an
external audio codec called ALC5616, and Figure 8 shows the audio codec circuit.
The Mini PCIe EVB provides several analog audio interfaces. J401 and J404 are used for module PCM
function which is connected through codec ALC5616. J402 and J403 are used for UC15 Mini PCIe analog
audio function only. This chapter gives a detailed introduction on these analog audio interfaces.

3.8. Jumpers
Mini PCIe EVB provides jumper J304 and jumper J405 to match up the UART’s and PCM’s level with Mini
PCIe module. The following table shows the jumper operation of J304/J405.
Table 11: Jumper Operation of J304/J405
1. By default, Jumper J304 is set to UART and 3V, and Jumper J405 is set to PCM and 1.8V.
2. If you want to enable W_DISABLE# function, please connect W_DISABLE and GND by the reserved
Jumper J103.
3.9. Test Points
Mini PCIe EVB provides some test points for some signals. It can help to obtain the corresponding
waveform.

4 Operation of Mini PCIe Module
4.1. Power On Mini PCIe Module
1. Connect the Mini PCIe module to the connector J101 on Mini PCIe EVB, charge with USB cable or
+5V power adapter and insert SIM card to J303.
2. Switch S201 to ON state, D103 will be light and indicates power supply for EVB is ready. The module
will be powered on automatically. D101 (NET_STATUS) will be light after the module registered to the
network successfully.
Table 13: Indication of D101
4.2. Power Off Mini PCIe Module
There are two ways to power off Mini PCIe module.
One way is to execute AT command AT+QPOWD (Refer to document [2]). It is the best and safest
approach. It logs off the network and saves data before shutdown. But Mini PCIe module will be powered
on again after shutdown.
The other way is to switch S201 (POWER) to OFF state directly, but this way is not recommended. Please
switch S201 to OFF after shutting down the module by executing AT command AT+QPOWD.

4.3. Reset Mini PCIe Module
The emergency restart option is only used in case of emergency. For example, the software does not
respond for more than 5 seconds due to some serious problems.
Pressing the key S101 for more than 150ms then releasing will reset the Mini PCIe module. This may
cause the loss of information stored in the memory since the reset has been initialized.
4.4. Communication via USB or UART Interface
4.4.1. Communication via USB Interface
1. Power on the Mini PCIe module.
2. Connect EVB and PC with USB cable through USB interface, refer to document [1] to install USB
driver from the Driver Disk.
3. Configure AT Command Window, select correct communication port, and operate the Mini PCIe
module via AT commands.
4.4.2. Communication via UART Interface
1. Install the USB-to-RS232 driver from the Driver Disk.
2. Connect the UART interface to PC with USB-to-RS232 converter cable.
3. Configure AT Command configuration tool, set correct baud rate (such as 115200bps) and COM
number which can be checked by the Device Manager on PC.
4. Power on the Mini PCIe module and operate the module via AT commands.
4.5. Firmware Upgrade
Mini PCIe Module upgrades firmware via USB port by default, please follow the procedures below to
upgrade firmware.
1. Open the firmware upgrade tool “QFlash” in the PC and power on the Mini PCIe module.
2. Click the “COM Port” dropdown list and select the USB DM port.
3. Click the “Load FW Files” button to choose the firmware document package.
4. Click the “Start” button to upgrade the firmware.
