From the project
SpinalHDL code to drive a 64*64 pixel HUB75E module with an ICE40
This code is used to drive a HUB75E dislay, fast enough to display animated gifs:
This project uses SpinalHDL, see installation notes here: https://spinalhdl.github.io/SpinalDoc-RTD/SpinalHDL/Getting%20Started/index.html
To build, yosys and nextpnr are used, see installation notes here: http://www.clifford.at/icestorm/

HUB75E ICE40: common questions
What microcontroller does the HUB75E ICE40 use?
The HUB75E ICE40 is built around the ICE40UP5K-SG48ITR, from the FPGA family.
How big is the HUB75E ICE40 PCB?
The HUB75E ICE40 measures 50 × 37.3 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the HUB75E ICE40?
51 components, from 23 distinct parts. The full bill of materials is listed on this page.
Where can I download the HUB75E ICE40 design files?
From the riktw/HUB75E_ICE40 repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
