Hello,
I recently purchased this package (LED Video Wall Controller Set/Programmed for Adafruit LED Panels : ID 1453 : $299.95 : Adafruit Industries, Unique & fun DIY electronics and kits), but cannot get it to work. I'm pretty sure I have a bad sending card. I also realized afterwards that I cannot use sensors with it and am currently looking for a Plan B.
I need to have 5 of the 16x32 LED panels from Adafruit (Medium 16x32 RGB LED matrix panel - 6mm Pitch : ID 420 : $24.95 : Adafruit Industries, Unique & fun DIY electronics and kits) to work off one FPGA / Arduino or Raspberry Pi or BeagleBone system. I am looking to make an animated face that changes based on voice commands.
Below are the options I've found so far, but don't know which would work or which would give me the best results. In the end, it has to work with sensors and control all 5 LED panels. In my mind, the eyes (two panels each) would be separate animations, but the mouth (3 panels) would be a single animation. Make sense? I'm leaning toward the Papilio Pro LX9 or the Logi-Bone.

FPGA Logi-Bone: LOGI Bone (retired) on ValentF(x)
Other options? Advice?
Thanks for any help ya'll can offer!
I really have no opinion as far as which board would be better for your needs. I'm very new to all this. I just got a DE0-Nano - Altera Cyclone IV FPGA starter board from Mouser. It was a few dollars cheaper than buying it from Adafruit. I also got the medium 32 x 32 led matrix.from Adafruit. I'm hoping to learn to do animations.
Adafruit has a tutorial on using this board and their 16 x 32 matrix at.New Project | FPGA RGB Matrix | Adafruit Learning System. It doesn't use animation, though, The files for the tutorial are at GitHub - adafruit/rgbmatrix-fpga: Adafruit RGB LED Matrix Display Driver for use with FPGAs (written in VHDL). In the README there is mention of files used to do animation.I just came across it and haven't had time to look at the files.
There are youtube videos, but they are no longer available.
Hope this is of some value.

Thanks for the help. I'll be sure to check it out.
Thinking of other options.....
Does anyone think using ws2811 led strips would be easier? These have a nice density to the pixel spacing: Adafruit NeoPixel Digital RGB LED Strip 144 LED - 1m Black [BLACK] : ID 1506 : $59.95 : Adafruit Industries, Unique & fun DIY electronics and kits Think we could create a face with these and power/control them with an Arduino or Raspberry Pi?
Another option...
I could maybe use the Nootropic Backpack (Nootropic RGB Matrix Backpack Kit for 16x32 Panel : ID 1072 : $12.50 : Adafruit Industries, Unique & fun DIY electronics and kits) with the 16x32 LED panels. I was thinking I could make all the backpacks Slave Arduinos and use I2C or SPI to communicate between them and a Master Arduino Uno or Mega 2560 that controlls all of the slave panels. Make sense? Possible?
