How to connect the board?
The SmartG100 is designed for use with Mikroelektronika’s development systems. To make connection between
development system and SmartG100 use flat cable with IDC10 connector and make connection between 2x5 male
header on development system port and 2x5 male header CN1 on SmartG100. Which port on development system will
be used depends on position of MCU pins which are used for UART communication. When connection is established,
depending which development system is in use, turn ON appropriate switch on DIP switch SW1, Table 1.
Table 1: DIP switch SW1 position
In order to supply SmartG100 with power it is necessary to connect external power supply via AC/DC connector
CN1. Power supply voltage can be in range between 7 to 23V AC or 9 to 32V DC. As indication that power supply is
connected LED marked with POWER will be turned on. To connect microphone with SmartG100 use screw terminal
CN4 which is marked with MIC. On “GND” side of screw terminal connect minus phase, and on “IN” side connect plus
phase of the microphone. In order to connect speaker use screw terminal CN5 marked with SPEAKER. “-” side of screw
terminal is used for minus phase and “+” is used for plus phase of speaker. If you want to access Leon-G100 module
pins on SmartG100 board you can use marked pads CN6. To power up Leon-G100 module is necessary to press and
hold push button marked with “POWER ON GSM MODULE” for 1s.
How to use the board?
In order to use SmartG100 connect antenna with Leon-G100 module, Figure 1. Connect power supply via AC/DC
connector and now connect SmartG100 with development system as described in previous section. Write program and
upload it to MCU on development system. Program example can be found on:
