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 hoping to make it available at a much lower cost than our previous FCDEV3B product.
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.
As of this writing (late November 2020), these Caramel2 boards are currently undergoing final assembly; once this final assembly is done, they will need to be thoroughly tested. We are hoping to bring these boards to public availability some time in December of 2020. In the meantime, we have published schematics and a photo of a partially assembled board.
