Hello FreeCalypso community, It has been 8 months since our Tango-based Caramel2 boards became publicly available, but so far no one other than me and Das Signal got one of these boards.
I have also put out some additional documentation. Most of our documentation for iWOW TR-800 and for our rebranding of this module as FC Tango has been published back in 2020-10: ftp://ftp.freecalypso.org/pub/GSM/iWOW/ ftp://ftp.freecalypso.org/pub/GSM/FreeCalypso/Tango/ More recently I have published the Gerber files from the PCB reverse eng company, showing the complete internals of the TR-800 module PCB: ftp://ftp.freecalypso.org/pub/GSM/iWOW/TR800-reverse-eng-gerbers.tar.bz2 Schematic-equivalent ueda-language source code producing a netlist that exactly matches all connected copper on that module PCB was already published earlier, along with my own assignment of reference designators: ftp://ftp.freecalypso.org/pub/GSM/FreeCalypso/Tango/FC-Tango-netlist.tar.gz ftp://ftp.freecalypso.org/pub/GSM/FreeCalypso/Tango/FC-Tango-component-placement.pdf And finally just today I wrote and published FC Caramel2 Status Report and User's Guide - a document that details exactly how our C2 project came out (what works perfectly vs. which parts have issues) and shows how to use the board at a basic level. Here it is: ftp://ftp.freecalypso.org/pub/GSM/FreeCalypso/Tango/Caramel2-SR-UG-v1.1.pdf And here is the schematic drawing for this board, in case you missed it when it was published last year: ftp://ftp.freecalypso.org/pub/GSM/FreeCalypso/Tango/caramel2-schem.pdf As a reminder, all of this hardware is still readily available: * Bare Tango modules (for building your own design around them) are $40 apiece, no MOQ; * Caramel2 boards go for $220 for a fully complete kit, or $150 for a reduced kit where you need to provide your own adapter(s) to two LVCMOS (2.8V or 3.3V) UARTs. I am also very open to the idea of giving this hardware out completely free of cost to anyone who can demonstrate some loyalty to the cause and mission of FreeCalypso - it doesn't do any good just sitting here, gathering dust. Hasta la Victoria, Siempre, Mychaela aka The Mother _______________________________________________ Community mailing list Community@freecalypso.org https://www.freecalypso.org/mailman/listinfo/community
