Hub75-adapter: common questions

What microcontroller does the Hub75-adapter use?

The Hub75-adapter is built around the PI, from the Raspberry Pi family.

How big is the Hub75-adapter PCB?

The Hub75-adapter measures 21.8 × 68.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Hub75-adapter?

8 components, from 7 distinct parts. The full bill of materials is listed on this page.

Where can I download the Hub75-adapter design files?

From the Knifa/pi2hub75 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Hub75-adapter design in my own project?

The repository has no license, so all rights stay with Knifa. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Hub75-adapter without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Raspberry Pi firmware against it before you order a PCB.
