iCE40-feather

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

Features

• 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.

Thanks

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

Revision History

• 0.1 used 0603 components, micro USB, and did not have the QSPI pins of the flash connected to the FPGA.
• 0.2 moved to 0402 components, USB Type-C, and broke all of the IO out whilst staying backwards compatible.
