    Awesome little intro to FPGA. I used it just fine with the Cu board.

    How many uarts can I setup with AU+? I'm hoping at least 4 to use for low speed (9600 BAUD) async sensors.

    I don't think the Au + FPGA schematic is correct. It shows the Au FPGA chip.

      I had this question too and asked Alchitry support. Their answer was that the schematics for both AU and AU+ are identical except for the FPGA, so they don't bother publishing a separate pdf. For the AU it's a xc7a35tftg256, and for the AU+ it's a xc7a100tftg256. Since they're both using the ftg256 package, both FPGA's have the same pinout and constraints file. I have confirmed this on the Xilinx site here: Artix-7 FPGA Package Device Pinout Files HTH.
