THE FIRST ICE40 FEATHERWING

There have been iCE40 Feathers, but now there is a FeatherWing! An FPGA companion board designed to be controlled directly by your favorite Adafruit Feather!

And.. How Chill! An icy edition to your feather wing collection brings a Lattice iCE5LP4K FPGA to your Feather'd shenanigans. Programmed over SPI, this FPGA feather wing brings every pin of the iCE5LP4K to 0.1" headers and the RGB open drain pins to a tiny yet bright RGB LED.

FPGA allow you to bring a whole new level of complexity to your design, providing the flexibility to introduce custom logic developed in verilog and built with fully open source tools. All designs in our current examples repository for the IcyBlue Feather are compatible, while also providing more available GPIO for expanded functionality.
