What is it?

Version 2 is here bringing major improvements including hardware bug fixes and USB-C! Brrr, is it cold outside? Nah, it's just the IcyBlue Feather! This unique FPGA feather allows you to easily get started with FPGA development with a highly capable and robust ICE5LP4K FPGA from Lattice Semiconductor! The ICE5LP4K brings two hardware I2C and SPI blocks, a bright RGB LED, two user LEDS, and 22 accessible GPIO through the headers of the feather board.

Programming is easy using an FTDI FT232HQ USB FIFO bridge, allowing you to quickly program the on board SPI FLASH with your bitstream hex or bin files. The FT232HQ makes this board compatible with both open source tools such as icestorm and proprietary tools like the Diamond Programmer provided by Lattice Semiconductor.

The feather form factor developed by Adafruit also means that this project is mobile with battery power. This is particularly useful for developing on the go and mobile deployments of your FPGA projects.

Whether you are a first time FPGA developer or a seasoned professional, the IcyBlue Feather brings a powerful and capable yet compact FPGA to your bench.

Why did you make it?

IcyBlue brings the best of an iCE40 FPGA and the Adafruit feather form factor to provide a vast environment of sensors and add ons. This makes it easier than ever to learn FPGA design.
