MAX7 Proto

Prototyping Board for Altera MAX7000 CPLDs

Introduction

MAX7 Proto is a prototyping board based on Altera MAX7000 series CPLDs. The board has pin headers on both sides, and it can be easily mounted on a breadboard. It also includes a 3.3V LDO, so that MAX7000AE CPLDs can be used. A DIP-8 oscillator socket is provided for the designs that requre a clock.

Questions

How big is the Max7 proto PCB?

It measures 20.3 × 52.1 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Max7 proto use?

23 parts, built around the EPM7064AETC44-7. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Max7 proto KiCad files?

From the skiselev/max7_proto repository on GitHub, at the commit this page was made from: the board is KiCad/MAX7_Proto.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Max7 proto design in my own project?

Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
