Dancing dots: common questions
What microcontroller does the Dancing dots use?
The Dancing dots is built around the ICE40HX4K-TQ144, from the FPGA family.
How big is the Dancing dots PCB?
The Dancing dots measures 375.4 × 188.5 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Dancing dots?
1349 components, from 8 distinct parts. The full bill of materials is listed on this page.
Where can I download the Dancing dots design files?
From the softminus/dancing_dots repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Dancing dots design in my own project?
The repository has no license, so all rights stay with softminus. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Dancing dots 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.
