Maison JP DJ: common questions

What microcontroller does the Maison JP DJ use?

The Maison JP DJ is built around the ATMEGA8A-A, from the AVR/Arduino family.

How big is the Maison JP DJ PCB?

The Maison JP DJ measures 96.9 × 99.9 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Maison JP DJ?

100 components, from 32 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 Maison JP DJ design files?

From the Antoine-GG/Maison_JP_DJ 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 Maison JP DJ design in my own project?

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

Can I test firmware for the Maison JP DJ without the hardware?

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