About the Copy PCB

Copy is an open source PIC PCB design by ProbablyNotArtyom, published on GitHub under the GPL-2.0 license. It is a 4-layer board measuring 214 × 170 mm, with 184 components from 60 distinct parts.

Its main chip is the PIC24FJ256DA210-IPT, from the PIC family. Other key parts include the 74LS148, 74LVC245APW, M68030, SIMM_72 and 74LS245. By type, the board carries 67 resistors, 58 capacitors, 31 ICs, 12 connectors, 5 crystals and 2 switches.

From the project

Blitz is a 68030 based homebrew computer I designed over the course of nearly 3 years, starting in late 2017.

Blitz runs my 32-bit operating system G-DOS. It supports FAT filesystems, and uses a flexible driver & init subsytem that handles hardware interfacing. G-DOS has my custom shell (G-Shell) and monitor (G-Mon) built-in, and boots directly from the onboard Flash ROM. A CGA card can be installed in an ISA slot to provide video output, and is required to use Blitz effectively. Lastly, it includes a bootloader that can load & bootstrap a Linux kernel off a disk.

Copy: common questions

What microcontroller does the Copy use?

The Copy is built around the PIC24FJ256DA210-IPT, from the PIC family.

How big is the Copy PCB?

The Copy measures 214 × 170 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Copy?

184 components, from 60 distinct parts. The full bill of materials is listed on this page.

Where can I download the Copy design files?

From the ProbablyNotArtyom/Blitz repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Copy design in my own project?

Yes, under the terms of its GPL-2.0 license, which ProbablyNotArtyom chose for the repository.

Can I test firmware for the Copy 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.
