MOD Expression pedal hardware repository

Legacy mod-hw-expression-pedal =======================

This repository contains the schematics and PCB design files for the Expression Pedal hardware. This is a peripheral meant to be used in conjunction with MOD (http://moddevices.com/) via its control-chain interface.

These files were created and can be improved with KiCAD, a free software Electronics CAD which is available at http://www.kicad-pcb.org/

Cc hw expression pedal-LEGACY: common questions

What microcontroller does the Cc hw expression pedal-LEGACY use?

The Cc hw expression pedal-LEGACY is built around the LPC111X_LQFP48, from the NXP family.

How big is the Cc hw expression pedal-LEGACY PCB?

The Cc hw expression pedal-LEGACY measures 78.4 × 40 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Cc hw expression pedal-LEGACY?

71 components, from 31 distinct parts. The full bill of materials is listed on this page.

Where can I download the Cc hw expression pedal-LEGACY design files?

From the mod-audio/cc-hw-expression-pedal-LEGACY repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Cc hw expression pedal-LEGACY design in my own project?

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

Can I test firmware for the Cc hw expression pedal-LEGACY 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.
