Figure 24: Modifications and Configurations for Current Consumption
1. Disconnect or remove R0145 and R0146.
2. Set the power switch (S0201) to the
PWR_ON
or
PWR_OFF
side, and set PWRKEY (S0101) to the
ON
side. Please note that you will get the current consumption of the module in sleep mode at USB
3.0 when S0201 is on the
PWR_ON
side and that in sleep mode at USB 2.0 when S0201 is on the
PWR_OFF
side.
3. Insert an applicable module (e.g., RM500Q-GL) into the M.2 connector (J0101).
4. Connect an external power supply to the oval vias marked by the reference designators, VCC and
GND, on the edge of the board to power the module independently. Then turn on the external power
supply, and the module will turn on.
5. Connect the USB interface (J0601) to the USB 3.0 interface of a PC.
6. Send
AT+QSCLK=1
and
AT+CFUN=0
to enable the module to enter sleep mode. After the module
enters sleep mode, you can test the current consumption from the external power supply.
