Hello FC community, Although our Caramel2 boards are not in the state of final assembly yet, I do have a picture of a partially assembled C2 board which I can share:
https://www.freecalypso.org/members/falcon/Caramel2/c2-partially-assembled.jpeg On this partially assembled board the Tango module and the RF plumbing piece sit loosely (they aren't soldered like they will be in the final assembly), and the microcoaxial end of the RF plumbing pigtail is not connected to the Tango module like it will be in the finished product: this particular board is intended to serve as a programming station for "bare" Tango modules, thus it has no functional RF plumbing. Finished Caramel2 boards will differ as follows: the SMA end of the RF plumbing piece will be secured to the board with soldered legs, the microcoaxial end of the same pigtail will be snapped onto the UMC antenna connector on the bottom of the Tango module, and then that Tango module will be mounted on the C2 board and also permanently secured with soldered legs. The Calypso chipset on the Tango module lives in the 2 mm vertical space between the top surface of our C2 PCB and the bottom surface of the Tango module PCB, and the mated microcoaxial connection will also be contained in the same 2 mm vertical space, permanently clamped in its proper place by the soldered attachment of the Tango module to the carrier board. I will be taking our current partially assembled C2 boards back to Technotronix for final assembly next Tuesday (Nov 17), and I was told to expect about one more week of turnaround time from that point - thus hopefully we will get fully assembled C2 boards toward the end of November. Assuming that they pass all of the tests to which they will be subjected (including RF tests on our CMU200 station in all 4 GSM frequency bands), these boards will then be made available to the public. Assuming that we don't get bit by any yield issues, the prices will be the same as announced earlier: $150 for a basic kit consisting of a Caramel2 board, a power supply and an antenna (you have to provide your own 2.8V or 3.3V UART adapter), or $220 for a full kit including the above plus our DUART28 adapter and interconnecting ribbon cable. And here are some pictures of our Luna LCD and keypad add-ons: https://www.freecalypso.org/members/falcon/Caramel2/lcd-board.jpeg https://www.freecalypso.org/members/falcon/Caramel2/keypad.jpeg The ribbon cables that come out of the LCD board and the keypad board connect to the 56-pin expansion interface on our Caramel2 board (unchanged from iWOW's DSK board to which these Luna add-ons originally connected); the LCD board also has a separate pair of wires connecting backlight power - Caramel2 has a dedicated 2-pin header for this bl power connection as well. The LCD displays TI's original 176x220 pixel color UI in its full glory when the board runs our FC Tourmaline firmware. In physical terms the keypad is a fully generic 5x5 matrix of rows and columns, devoid of any logical function; the only feature of our keypad board that assigns logical functions to buttons is my choice of PCB silk screen labels - these "silk" labels assign logical functions to keypad buttons, and they have been assigned to match the buttons on TI's D-Sample handset. The Pirelli DP-L10 also happens to have exactly the same set of main keypad and side buttons as D-Sample, thus our Luna keypad can also be thought of as equivalent to Pirelli's, for anyone who prefers to view it this way. Hasta la Victoria, Siempre, Mychaela aka The Mother _______________________________________________ Community mailing list Community@freecalypso.org https://www.freecalypso.org/mailman/listinfo/community
