About the Body2 PCB

Body2 is an open source NXP PCB design by mattybrad, published on GitHub. It is a 4-layer board measuring 90 × 95 mm, with 180 components from 49 distinct parts.

Its main chip is the TEENSY4.1, from the NXP family. Other key parts include the TCA9548APWR, TL072, SGTL5000XNLA3, TPS54331DR and AP7313-18SAG. By type, the board carries 67 resistors, 63 capacitors, 19 jumpers, 10 ICs, 10 connectors and 7 diodes.

It belongs with the audio designs in this gallery.

From the project

A synthesizer/guitar hybrid. Somewhere between a MIDI guitar and a synthesizer. Not commercially viable. A time sink. A rabbit hole. An obsession. A mistake. An exercise in blind faith. A reason to tidy the shed. A sequel to a glass cannon.

Body2: common questions

What microcontroller does the Body2 use?

The Body2 is built around the TEENSY4.1, from the NXP family.

How big is the Body2 PCB?

The Body2 measures 90 × 95 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Body2?

180 components, from 49 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Body2 design files?

From the mattybrad/bjarkardottir2 repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Body2 design in my own project?

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

Can I test firmware for the Body2 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.
