Hi everybody,

in the mean time I've got two suggestions by Digilent and Numato.

Digilent suggest Nexys 4 in a very short mail (I guess this one:

Numato suggest this one: http://numato.com/waxwing-spartan-6-mini-module
together with an development board, which is currently in pre-release state:

>>The development board (Minimudule needs to be installed on this board)
>> has the following features.
>>* Power supply necessary for all logic and peripherals
>>* FT2232 USB Communication
>>* 4x PMOD compatible connectors
>>* 1 HDMI connector (buffered)
>>* 1 VGA connector
>>* 16x2 alphanumeric LCD
>>* 2x 7 segment LED displays
>>* 8 general purpose LEDs
>>* 8 Microswitches for user input
>>* 1 dip switch
>>* Onboard SPI flash programming support (No need of platform cable for configuration)
>>* JTAG connector
>>* SD card slot
>>* PWM Audio out jack

Does somebody with more experience in FPGA have an opinion?

I am tempted to give Numatos Waxwing a try ...
