About the SuperAudioBoard PCB

SuperAudioBoard is an open source NXP PCB design by whollender, published on GitHub under the CC-BY-4.0 license. It is a 4-layer board measuring 88.9 × 68.6 mm, with 174 components from 50 distinct parts.

Its main chip is the TEENSY_3_1, from the NXP family. Other key parts include the SI8662BC, SI8602AC, CS4272, OPA2348 and THS4521. By type, the board carries 80 capacitors, 60 resistors, 13 ICs, 11 inductors, 5 relays and 2 diodes.

It belongs with the audio designs in this gallery.

SuperAudioBoard: common questions

What microcontroller does the SuperAudioBoard use?

The SuperAudioBoard is built around the TEENSY_3_1, from the NXP family.

How big is the SuperAudioBoard PCB?

The SuperAudioBoard measures 88.9 × 68.6 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the SuperAudioBoard?

174 components, from 50 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 SuperAudioBoard design files?

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

Can I use the SuperAudioBoard design in my own project?

Yes, under the terms of its CC-BY-4.0 license, which whollender chose for the repository.

Can I test firmware for the SuperAudioBoard 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.
