From the project
The basic idea behind this project is to create a simple breakout of an ICE40 FPGA with some LEDs and Buttons to interact with the FPGA and enough resources to run a simple softcore, like a small RISC-V core. Therefore a SRAM will be added in case the internal memory blocks are n
The basic idea behind this project is to create a simple breakout of an ICE40 FPGA with some LEDs and Buttons to interact with the FPGA and enough resources to run a simple softcore, like a small RISC-V core. Therefore a SRAM will be added in case the internal memory blocks are not big enough, The configuration SPI flash may be used to store programm data for the softcore. So this board can be used for teaching basic FPGA, microcontroller and CPU architecture topics.

Iceduino: common questions
What microcontroller does the Iceduino use?
The Iceduino is built around the ICE40HX4K-TQ144, from the FPGA family.
How big is the Iceduino PCB?
The Iceduino measures 80 × 100 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Iceduino?
241 components, from 65 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 Iceduino design files?
From the RubenVoell/iceduino repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Iceduino design in my own project?
Yes, under the terms of its CERN-OHL-1.2 license, which RubenVoell chose for the repository.
Can I test firmware for the Iceduino 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.
