just came across this
http://www.indiegogo.com/projects/navspark-packing-32bit-features-and-gps-gnss-into-8bit-size-and-price/x/533586dev is done by SkyTraq which is ,
according to this blog, a fabless semiconductor company, which develops GPS chipset for consumer navigation and tracking applications
they have 3 boards
15$ "NavSpark" advertised as "low cost GPS / GNSS board with a 32-bit LEON3 SPARC V8 MCU that can be programmed with the Arduino IDE. "
17$ "NavSpark-BD" is GPS + Beidou
17$ "NavSpark-GL" is GPS + GLONASS
difference seams to be in the binaray blob they use, they claim to "NavSpark hardware design files (schematic, board design, and bill of materials) will be released and made available to users. Source code of the customized Arduino IDE will also be made available; the GPS / Beidou / GLONASS navigation kernel library integrated will remain in library file format. Users are free to extend, adapt and redistribute the hardware and software for any projects, commercial or non-commercial. "
anyway, even if they are still a long shot away of funding and not sure if there is much "headroom" left in the main "100MHz 32bit RISC/FPU," after all the gps processing,
but hey, for 17$ it might be a nice thing to dabble with if this comes of the ground.
they are bit stupid, the one piece items are only "early bird" solde out and next up you need to get 2
not sure why they don't add perks for 20usd/ 22 used or so for 1
