From the project
1 circuit board design a day for 31 days.
The icebreaker is a friendly development board for the iCE40: https://github.com/icebreaker-fpga/icebreaker
The icebreaker is a really nice and handy little board. But it has a small flaw, the ice40 FPGA it uses is quite smol, while it's often fun to see the exciting projects people pull off with 5k LUTs. Sometimes it's handy to have a bit of extra space available whe experimenting.

ECPBreaker: common questions
What microcontroller does the ECPBreaker use?
The ECPBreaker is built around the LFE5U-12F-7BG256I, from the FPGA family.
How big is the ECPBreaker PCB?
The ECPBreaker measures 50 × 37 mm, has 6 copper layers and is 1.6 mm thick.
How many components are on the ECPBreaker?
117 components, from 50 distinct parts. The full bill of materials is listed on this page.
Where can I download the ECPBreaker design files?
From the gregdavill/advent-calendar-of-circuits-2020 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the ECPBreaker design in my own project?
The repository has no license, so all rights stay with gregdavill. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the ECPBreaker 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.
