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.

Questions
How big is the ICE40-fpga PCB?
It measures 50 × 22.9 mm and has 4 copper layers, 1.6 mm thick.
What parts does the ICE40-fpga use?
69 parts, built around the ICE40UP5K-SG48ITR50, W25Q32JVZPIQ, 93C46B/P and AP2112K-3.3. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the ICE40-fpga KiCad files?
From the joshajohnson/iCE40-feather repository on GitHub, at the commit this page was made from: the board is hardware/0.1/iCE40-fpga.kicad_pcb and its schematic hardware/0.2/ftdi.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ICE40-fpga design in my own project?
Its repository states no licence, so its author keeps all rights: ask joshajohnson before reusing the design.
