Amp board: common questions

What microcontroller does the Amp board use?

The Amp board is built around the PIC24FJ128GL306-I/PT, from the PIC family.

How big is the Amp board?

The Amp board measures 223.5 × 147.3 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Amp board?

674 components, from 145 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 Amp board design files?

From the Alex-Wolfe/Home-Audio-System 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 Amp board design in my own project?

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

Can I test firmware for the Amp board without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug PIC firmware against it before you order a PCB.
