FreeCalypso Caramel2 is a development board built around our Tango core module. This development board has been designed with the following three modes of usage in mind:
For anyone who is designing and building their own higher-level hardware products and who is looking to incorporate our Tango module as a component into their design (vertical market applications), Caramel2 can be used as an evaluation board for Tango, allowing prospective vertical market customers to exercise our module, to see it working, and to learn hands-on how to work with its various interfaces.
If you are not a prospective vertical market customer, but a personal enthusiast tinkerer with an interest in GSM and in FreeCalypso, and if you are interested in a FreeCalypso development board for general hobbyist use, then Caramel2 may be a good choice, as we are able to sell it at a much lower price than our original FCDEV3B product. (FCDEV3B is still available and will always remain so, but it is more expensive.)
Anyone who wishes to follow Mother Mychaela's work on the FreeCalypso handset project can do so using a Caramel2 board to run our work-in-progress handset firmware; Luna LCD and keypad add-ons are also required in this case.
Our Caramel2 boards are currently available at $220 USD apiece; this price is for a complete kit consisting of:
- Caramel2 motherboard
- Power supply brick (universal AC to 3.6 VDC)
- DUART28 adapter
- Ribbon cable connecting Caramel2 and DUART28 boards
- SPK WTH43006 antenna (5 cm long, straight)
As far as documentation goes, we have published schematics for this development board. Further documentation will be written if and only if there is any interest.
