About the Body PCB

Body is an open source NXP PCB design by mattybrad, published on GitHub. It is a 4-layer board measuring 90 × 120 mm, with 289 components from 46 distinct parts.

Its main chip is the TEENSY4.1, from the NXP family. Other key parts include the TL072, SGTL5000XNLA3, TPS54331DR and AP7313-18SAG. By type, the board carries 63 capacitors, 48 resistors, 9 ICs, 7 connectors, 7 diodes and 4 inductors.

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.

Body: common questions

What microcontroller does the Body use?

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

How big is the Body PCB?

The Body measures 90 × 120 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Body?

289 components, from 46 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 Body 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 Body 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 Body 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.
