Board information
The
GSM Booster
board is a replacement for Telit GM862-QUAD module and can be
used on already supported development systems such as SmartGM862, PICPLC16
v6 PLC system, PICPLC4 v6 PLC system, EasyGSM/GPRS GM862 or AVRPLC16
v6 PLC system. It contains Telit
GL865-QUAD
GSM module, MMCX GSM antenna
connector, SIM card holder and CSTP 50 pin vertical SMD molex connector (male)
for further connection. Before you insert SIM card into SIM card holder make sure
that it is properly oriented,
Figure 1
(opposite to GM862-QUAD). Then push the
card slowly until you hear the "click" sound. If you want to remove the card, push it
until you hear the "click" sound and then pull it out. Improper use may damage your
card. There are four zero-ohm SMD jumpers used to select whether Handsfree (HF)
or Handset (MT) audio pins are used. Jumpers are soldered in the HF position by
default. SIM card and GSM antenna are not included in the package.
