When it arrived i ordered a breakout board kit so i can hook it up to breadboard and experiment with logisim's Verilog conversion, so i haven't done anything except a blinking light program yet. So far everything looks good with the board, the documentation is good, and the shipping speed was fast. Communication between the seller however is non-existent at the moment, and you will probably be on your own even on the forums. Didn't look at dimensions when i purchased it and was pleasantly surprised to find it much smaller than i expected. The FPGA on it is smaller than a pill!
The TinyFPGA BX is exactly what I was hoping for in an FPGA platform. No bloat, a readily deployable module when paired with only the specific hardware your application needs. The software was trivial to setup in Linux, and was documented quite well. Additionally, Luke has been extremely helpful and quick to respond when people raise issues they are having on the forums for the product. I would wholeheartedly recommend this to anyone who wants a small, general purpose FPGA for personal projects. This product sits in the same product space that the old Digilent CMOD once occupied, but is easier to use, faster to deploy, and avoids the monstrous bloat associated with Xilinx tools.
