ICEBreaker+++
About the ICEBreaker+++ PCB
ICEBreaker+++ is an open source FPGA PCB design by gregdavill, published on GitHub. It is a 4-layer board measuring 56 × 37 mm, with 104 components from 46 distinct parts.
Its main chip is the LFE5U-12F-8BG256C, from the FPGA family. Other key parts include the 93LC46BT-I/OT, FT2232HQ-TRAY, W25Q32JVSSIQ TR, TLV62569DRLR and TLV713285PDBVR. By type, the board carries 43 capacitors, 27 resistors, 14 connectors, 10 ICs, 5 diodes and 4 inductors.
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.

ICEBreaker+++: common questions
What microcontroller does the ICEBreaker+++ use?
The ICEBreaker+++ is built around the LFE5U-12F-8BG256C, from the FPGA family.
How big is the ICEBreaker+++ PCB?
The ICEBreaker+++ measures 56 × 37 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the ICEBreaker+++?
104 components, from 46 distinct parts. The full bill of materials is listed on this page.
Where can I download the ICEBreaker+++ 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 ICEBreaker+++ 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 ICEBreaker+++ 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.
