Retro-002: common questions

What microcontroller does the Retro-002 use?

The Retro-002 is built around the Reset, from the AVR/Arduino family.

How big is the Retro-002 PCB?

The Retro-002 measures 100 × 100 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Retro-002?

295 components, from 42 distinct parts. The full bill of materials is listed on this page.

Where can I download the Retro-002 design files?

From the githubgilhad/HW-001 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Retro-002 design in my own project?

Yes, under the terms of its GPL-3.0 license, which githubgilhad chose for the repository.

Can I test firmware for the Retro-002 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.
