4.6. Current Consumption Test
The EVB can also be used to test the current consumption of the module after being modified and
operated by the following steps.

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.
