From the project

iCE40UP5K in an Adafruit Feather form factor

iCE40 Feather is a Lattice iCE40UP5K FPGA in the Adafruit Feather form factor.

- Lattice iCE40UP5K FPGA. - 20 IO in the standard Feather pinout. - 6 extra IO on AREF and extra pads on back of board. - FT2232 enables both programming and communications over UART through a Type-C USB connector. - QSPI flash. - Onboard RX/TX, user, and RGB LEDs.

- Key parts of this board were based off the iCEBreaker project. - Tisham Dhar was the driving force behing the 0.2 redesign.
