This is the first I hear of these Sim900 boards. Are there any other boards like it? Possibly 3G compatible models or slimmer versions with just soldering leads instead of jacks? I guess you could easily remove the jacks anyway if you needed to.
Combined with some of the slimmer boards out there (like one of the many old Allwinner sticks or Gumstix), this could actually be used to build a real open source DIY phone platform.
- coffeecheque 13y agoI've used the SIM900 boards a few times for a few moments with Arduino project. They are good and simple, but as you say not 3G (only GSM). I assume the 3G modules are different or not as in demand by Chinese manufacturers, which is why I haven't seen any on eBay when I go looking. I'd love a simple, cheap 3G module. It'd make the coverage better for a start.
- pjc50 13y agoSierra Wireless have 3G modules, although they're not particularly simple or cheap.
- mschuster91 13y agoSome Huawei data sticks carry phone-capability according to their "Mobile Partner" software (there's support for it in the disabled modules. Mobile Partner is a pile of shit but sometimes it's actually useful). I do not know however which exact sticks can do this.
- userbinator 13y ago3G module with bonus GPS: http://www.ebay.com/itm/261346638302 http://www.ebay.com/itm/261346638302 Appears to be a Qualcomm QSC6270-based module.
- swimfar 13y agoThat listing is blocked in France due to "legal restrictions". Is it a module designed for laptops, or something more general?
- userbinator 13y agoIt's this: http://wm.sim.com/producten.aspx?id=1029 http://wm.sim.com/producten.aspx?id=1029
- frik 13y agoCould one solder this 3G module on the board from the article? http://www.micro4you.com/store/sim900-gprs/gsm-module.html http://www.micro4you.com/store/sim900-gprs/gsm-module.html (just removing the GPRS module and soldering the 3G?)
- userbinator 13y agoNot possible, SIM900 has 68 pins and SIM5320 has 80.
- seba_dos1 13y agoThere are lots of them. Just look at what GTA04 and Neo900 are using (Option and Cinterion). Such project can't accept closed baseband being highly integrated with main CPU and RAM like most of modern smartphones do, so they use ready 3G/LTE modules to move it out as a USB peripheral in CPU perspective.
