And how can I make the same so that I use a range of input 3-12V and output is same as my input?

Yes of course (TTL 3.6V)

I believe SIM900 is quadband, hence suited for US.

Thank you for sharing that info Patricio – I am looking for similar thing – did you happen to find how to avoid the MCU and take advantage of SIM controlling its own outputs directly? – Please share any pointers you may have come across on those lines. Thx in adv.

Thank you for sharing the info, ahmetalncak. It is helpful. So, the pins 12, 14 (TXD and RXD) on this board can work directly with MCUs like ATMEGA etc. from freeduino, right?

hi,

thanks for your reply,i have read the datasheet for sim900,in that they mentioned 2 capacitors only for battery connection,is it enough or 4 capaciotors are required?and if required can u please tell me the functioning of remaining 2 capacitors.

thanks in advance.
