sim300 v3.04

Hello,
I have designed my board as per V2[1].01 for SIM300.
But I am not getting whetherVext is out put pin or input.
The voltage ranges I am getting on designed board are
Vbat = 4.6V
Vext =3.01 if I attached D202 output on Vext pin considering Vext is input pin.

I am not getting any indication on network status LED connected on pin no-30.
I am not getting what to do please help....

Hi...

The VBAT range for SIM300 is 3.4 ~ 4.5V. It is recommended to supply 4V.

You are pumping 4.6V which is out of the range.
Try to reduce the voltage supply and observe again...

Hi,

I purchased a SIM300 module without considering the connections. The tiny connector which i ordered with it is ment to be connected to a special PCB or something similar.

Can any one explain how i can obtain the serial port and power connections from this module? From where i can get the necessary hardware.

Thank you.

Can I use LM317 to supply power for SIM300C module?
Can it send and receive SMS with 1.5A current supply?

sim300_v7.03 datasheet

Hi,


I would like to know how to connect my GSM module (SIM300) to my microcotroller (PIC 18F4525) ??. I have to command the GSM module so that it dial a number if an input of the PIC 18F4525 is activated, aslo the SIM300 should be able to activate a relay (in the outputs of the Microcontroller) by AT command ?


thanks in advance.

Does any one can give me "working" voltage specification for the sim300,
VBAT, VEXT, SIMVDD?

the voltage output value of XC6019B302MR ?

So how does one get hold of these for cheap? I mean most places ask more than what the module itself is worth
