Charge golden capacitor or battery when VBAT is applied.
3. The width of VBAT trace is recommeded to be more than 2mm.
2. Module drains the maximum current around 1.6A in burst time (577us).
If unused, keep VRTC open.
1. VBAT ranges from 3.3V to 4.6V.

Module Design
As only powering the VRTC pin to keep the RTC will lead
an error for about 5 minutes a day, it is recommended
to power VBAT and VRTC pin at the same time when
RTC function is needed.
the max voltage drop during
the burst transmission
does not exceed 400mV.
The voltage range of ADC input channel is from 0 to 2.8V.
Please select a high-precision divider resistance.
4. Capacitance is arranged in ascending order, with the smallest one closing to the VBAT pins,
and all capacitance as close to the VBAT pins as possible.
A Pi match circuit is recommended to be added.
For RF layout, please refer to
RF_Layout_Application_Note.
Don't change those interface for other uses.

LDO Application
DC-DC Application
The voltage converter should provide a minimum current of 2.0A.
It is used when the DC input voltage is below 7V.
1. It can be used when the input voltage is above 7V in vehicle application.
eg. DC12V IN DCDC DC 5V OUT LDO
DC 4V OUT FOR
2. Use DCDC to convert high input voltage to 5V and LDO will generate
4V & 3.3V typical voltage for the module.

SIM Card Interface
NOTES
1. The value of C401 and C402 should be less than 1uF.
2. U401 and U402 is used for protecting SIM card against ESD, and the junction capacitance should be less than 50pF.
3. For MC60 module, ground of SIM card is recommended to be routed to the Pin 16("SIM_GND") of the module separately.
It should be placed nearby SIM card holder.

Connection of All Functional UART Port for 3.3V System
1. CTS&RTS will be used for HW flow control when mass data has been sent.
2. When AT+QSCLK=1 is set on the module, customer's application can
control the module to enter into or exit from the sleep mode through the pin DTR.
When DTR is set to high level, and there is no on-air or hardware interrupt,
such as GPIO interrupt or data on serial port, the module will enter into sleep
3. RI will output an indication signal when activity such as voice call or SMS
