Hi, Jean-Claude! Why does the new v5 board not have headers for the PSIX pins? The Arduino documentation implies that I2C needs to run on those pins, and lots of your plugs work as I2C. Am I missing something obvious, or were you just looking at the v5 for specialized applications? It looks like the USB version has them, and I'd be more likely to use USB instead of FTDI anyway.
Also, is Modern Device likely to start carrying the v5 or USB boards for us North Americans?
