Mainframe led tube: common questions

What microcontroller does the Mainframe led tube use?

The Mainframe led tube is built around the Teensy4.1, from the NXP family.

How big is the Mainframe led tube PCB?

The Mainframe led tube measures 99.1 × 116.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Mainframe led tube?

79 components, from 23 distinct parts. The full bill of materials is listed on this page.

Where can I download the Mainframe led tube design files?

From the lordiii/mainframe-led-tube repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Mainframe led tube design in my own project?

Yes, under the terms of its GPL-3.0 license, which lordiii chose for the repository.

Can I test firmware for the Mainframe led tube without the hardware?

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