which mesa card combo should i use?

Hi,

can someone recommend me some mesa card combo i should use?

I need to control 7 axis by analog signal so system require: 7 analog output channels, 7 uart channels ( i just need 7 RX channels to get serial data), 7 encoder channels.

I have experience in creating new bitfile, using mesa 5i25, 7i74, 7i83

for simple, i have plan to use x2 5i25 + 7i74 + x27i83. One for smart serial , the other for 7 UART channels and 7 encoder channels

which 5i24 card are you using? 5i24-16 or 5i24-25, actually i dont know what difference between them. My system requires a lot of IOs, how do i load firmware for 5i24 if i have 2-3 5i24 PCI cards in my PC ? And creating new bitfile for this card is same way as 5i25?

seem 5i24 is also reprogram card, so it needs to be flashed by mesaflash

The MESA 6I68 (shown here with 3X20 installed) is a simple motherboard for 3X2X series FPGA daughtercards that plugs into a standard one lane PCI-Express slot. The 6I68 provides a base and simplified I/O connections for the 3X2X series daughtercards. The 6I68 can be used for evaluation of 3X2X series cards or for final applications. The 6I68 buffers all I/O pins with quickwitches for 5V tolerance on all I/O, and provides jumpers for setting the 3X2X's VIO levels and configuration options. The 7I68 distributes the 3X2X's 144 I/O signals to six 50 pin .1" headers with standard Anything I/O pinouts. All signal are routed as differential pairs, allowing high speed differential signaling if desired.

is this board possible to use with combo 7i33TA and 7i44?Can i use Xilinx ise to creat a custom bitfile for it too?
