A work in progress KiCAD Schematic for an Arduino shield that supports 3 calculator networking. The shield footprint and schematic are in separate zip files. Put the Arduino shield files in the library path for KiCAD, and put the gCnBridge files in a project directory. There\'s a PDF of the schematic in there as well, although it's mostly the same as the schematic in the Calcnet documentation, apart from the connectors.
I\'ve cross checked with the Sparkfun zigbee shield, and that seems to use D2/D3 on the Arduino, so there\'s some compatibility there. WiFi seems to be a bit up in the air, the Sparkfun WiFi shield takes up most of the data lines. I haven't looked at the new, official Arduino shield yet, nor have I looked at the Ethernet shields yet.
I have 3 2.5mm connectors for serial connections to calculators, but I haven't broken out the calipers yet to figure out how many I can add to the end of the board, it may be a couple of more. I also don't have footprints yet for the 2.5mm connector I'm using, so that's coming.
