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.

ICE40-fpga: common questions
What microcontroller does the ICE40-fpga use?
The ICE40-fpga is built around the 93LC46BT-I/OT, from the FPGA family.
How big is the ICE40-fpga PCB?
The ICE40-fpga measures 50 × 22.9 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the ICE40-fpga?
62 components, from 42 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the ICE40-fpga design files?
From the joshajohnson/iCE40-feather repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the ICE40-fpga design in my own project?
It is published under CC-BY-NC-4.0, which limits how it may be reused; read the license before building on it.
Can I test firmware for the ICE40-fpga without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug FPGA firmware against it before you order a PCB.
