About the Mv2 base PCB

Mv2 base is an open source NXP PCB design by FOSDEM, published on GitHub. It is a 4-layer board measuring 69 × 64 mm, with 73 components from 41 distinct parts.

Its main chip is the Teensy41, from the NXP family. Other key parts include the TPS65130RGE and LM5158. By type, the board carries 27 capacitors, 19 resistors, 7 inductors, 6 diodes, 4 test points and 3 ICs.

It belongs with the audio designs in this gallery.

From the project

A full build needs several parts. All of these should be easily reproducible, while for the ones where we rely on an external manufacturer, we made sure to have ample spares.

A full build needs several parts. All of these should be easily reproducible, while for the ones where we rely on an external manufacturer, we made sure to have ample spares.

You will need one of each item, except when stated otherwise.

The case is an off-the-shelf widely available 1U case, made by Gainta.

We only use the actual enclosure. All other bits can be discarded.

Mv2 base: common questions

What microcontroller does the Mv2 base use?

The Mv2 base is built around the Teensy41, from the NXP family.

How big is the Mv2 base PCB?

The Mv2 base measures 69 × 64 mm, has 4 copper layers and is 1.592 mm thick.

How many components are on the Mv2 base?

73 components, from 41 distinct parts. The full bill of materials is listed on this page.

Where can I download the Mv2 base design files?

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

Can I use the Mv2 base design in my own project?

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

Can I test firmware for the Mv2 base 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.
