SIM Card Interface
NOTES1. The value of C501/C502 should be less than 1uF.
2. U501/U502 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.

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
