Dear reading IoTlers,
I've just come across this new kickstarter project from Spark IO: https://www.kickstarter.com/projects/sparkdevices/spark-electron-cellular-dev-kit-with-a-simple-data
Sounds pretty cool to me, but not convincingly cheap and until October is still a long time. So, I wonder if there are no other boards already available which might offer a similar hardware: Cortex-M + GSM/UMTS modem. Anyone with any hints?
Cheers, Oleg
Hello Oleg,
Not a Cortex but ARM7EJ-S, and no UMTS but only GSM, but Open Source and aimed to cost only 20$: http://www.kosagi.com/w/index.php?title=Fernvale_Main_Page (I mentioned this board previously on other occasions).
Cheers, Martine
Hi Oleg
interesting. Concerning IoT “network operators”, here’s something I came across recently, that is related: SIGFOX [1]. They use 868MHz band in Europe (and 900 band in the US), and rent space in cell towers (just like mobile network operators using GSM/UMTS etc.) to connect IoT devices to the Internet. Here’s an interview of one of their guys where he talks more about it [2].
Best,
Emmanuel
