INTRODUCTION
BOARD FEATURES
ELECTROSTATIC WARNING
BOARD USE REQUIREMENTS
The MOD-GSM board is shipped in protective anti-static packaging. The board
must not be subject to high electrostatic potentials. General practice for working
with static sensitive devices should be applied when working with this board.
Hardware:
Important: If your board does not work, first try to charge the battery as
MOD-GSM is excellent board for adding remote monitoring and control in remote
places by GSM cellular network. With this module you can use all the features of
each one of Olimex's boards with on-board UEXT connector by GSM network.
Also the board can work in stand alone mode, but only when the SIM card is
without PIN code. In stand alone mode MOD-GSM don't offer much opportunities.
It can receive information by GSM network, but if you want to operate with this
information, you will need appropriate board with UEXT connected to MOD-GSM.
Choose the other board depending on the application you want to have. MOD-
GSM contains quad-band GSM GPRS module 850/900/1800/1900Mhz inside
which covers most used GSM networks around the world. The GSM antenna is
build in the board so no need for external expensive GSM antennas.
