    An Arduino is nice for hobbyists only. Nevertheless it is much to expensive in comparision to Microchip chipKIT running on PIC32. Please find a table as below and compare yourself. On a ChipKIT (TDGL003 or TDGL002) you can get a Arduino ADK and several other ADKs as well. The operatating sytems could be a RTOS like FreeRTOS up to a small embedded Linux.


    Jelastic looks interesting but Nimbits at http://www.nimbits.com/ overs the same with much more options.

    Table with Arduino´s and clones

    The prices at the table are catched in November 2011 on Internet. The BUDGETARY prices of Microchip you can get by using their Microchip Advanced Part Selector . The parameters of the Microchip micro controllers are picked by cut  and paste. The technical data of the ATMEL are a manual selection from  the website of ATMEL. Please excuse mistakes. Any hint on mistakes are  welcome.

    The Arduino´s in the table and a long list of further Arduino clones are supported by adapter boards with wireless modules. The origin  Arduino´s are on 5 Volt. All clones I have seen are on 3 Volt. The  GSM/GPS adapter and further I will make public will support 5 Volt and 3  Volt CMOS level. A basic Arduino has one UART and one SPI only. Later  versions or clones offer more serial interfaces. Nevertheless one UART  you can drive one wireless module normally only. With the SPI it is  close the same. The new generation of adapters listed here (also called  shields) are supporting some kind of multiplexing. Based on this feature  it is possible to build “sandwiches” of several adapter PCBs on top of  an Arduino. Arduino´s are cheap. The clones are even cheaper. The  Ardunio clones of Microchip together with GSM/GPS adapter build the  cheapest evaluation kits for AVL (Automatic Vehicle Location) the world  ever have seen. My ignoring the GPS you get a inexpensive telemetry  playground. Everything is open source. Everybody can copy it. Last but  not least it is supported by engineering offices to redesign the Arduino  plus adapter board to one industrial PCB with switched DC/DC regulator  for example. The benefit is that the software development on Arduino  plus adapter can be processed parallel to the hardware development.

    If you are interested in a your own IOT, AVL, Smart Home, AAL, M2M or  M2M2P solution, then send an email to harald.naumann (at) gsm-modem.de  or give me a call at +49-1755774832. I will present you my experience  (25 year in radio / 15 years in GSM and GPS). On request you can get  references to wireless projects for all over the world. Thank you in  advance for any challenge.
