: HILONC-3GPS module top side
3.1. How to connect a SIM card
: SIM Card signals
The HILONC-3GPS module provides SIM signals to the 116 pins of the LGA. A SIM card holder with 6 pins
must be adopted to access SIM functions.
 Decoupling capacitors must be added on to the VSIM,SIM_DATA,SIM_RST,and SIM_CLK signals as close
as possible to the SIM card connector to avoid EMC issues and in order to pass SIM card approval tests.
Vsim must be used only for the SIM card.
 Use ESD protection components to protect the SIM card and module I/Os against electrostatic discharge.
The following schematic shows how to protect SIM access of the 6 pin connector. This must be performed every
time the SIM card holder is accessed by the end user.
