gsm module circuit design

Can you elaborate your problem please? "Gsm module" is not meaningful.Do you want to build an interface for your cell phone?

gsm module schematic

Companies such as Philips sell a chipset and also provide a referance design for their chipset. Just go to their website for design and layout information.

According to my knowledge GSM Module is much higher in cost then a simple mobile phone, eg, u can buy a second hand mobile phone in about 5$ to 10$, but GSM Module is not less then 50 dollars,
So my Question is that, can we use GSM Module avaiable is mobile phone set lets say i have LG KG275, nokia 1100, or any china mobile ?

note: i convert it from local currency rates

I agree with you. Because that I use cheap Siemens phones (2-3eur price) for SMS alarm, and SMS remote control.

Take phones with support of AT commands!

I try this Siemens phones with some projects :

S25, S35, S45, S55, C10, C35, C45, C55, C56, C60, C65, M35, M50, M55, ME45, MT50, SL45(i)
(I recommend C55, C60, C65, M55,... - From C55 to right)

Phones that do not support AT commands :

C25, A50 and all Siemens in serie A



This list is not complete list, this is just based on my expirience for now. There is more phones that supports AT commands, and phones which dont support.


Price of some commercial GSM modules, are to high, goes up to 150-300eur :roll::cry: its to high. This is just a part of project. In most cases that not worth it, because price ! Whole project will have value of 500eur, its to high. In market there is also other commercial GSM modules with price about 40-50eur, when you add other needed accessories to module nice amount of money goes from pocket. Of course all depends on the purpose of project and what you need or what you try to do.

Plus some GSM modem are huge consumer of power. Phone are not, phone also have battery. I make SMS alarm, SMS remote control and other such things to work over four AAA NiMh. SMS Alarm uses four AAA and consumes 6mA in standby operation, when sending SMS consumes 15mA and after sending SMS goes back to 6mA in standby. Charging of both phone and alarm 4xAAA batteries done with serie of small solar cells taken from solar garden lamps. :wink:


Some of older and first pictures of project, todays this goes to SMD (right now working on reduction of size and puting complete SMS alarm into phone, into battery space, and battery goes out like extern battery) :

I see some people on edaboard that uses some gsm modules about 300eur for some project. :-| I say Ok for that, but for learning or for some special role.

Solution must have easy implementation and be simplified as much as possible, must do the job, and must be reliable. Attention must be paid to the price of all parts (this not count if you are a millionaire). We all must learn from chinese production, and their logic.

But not like Del Boy from "Only Fools and Horses" best TV Show:
