M68k hbc: common questions

What microcontroller does the M68k hbc use?

The M68k hbc is built around the ATmega328P-P, from the AVR/Arduino family.

How big is the M68k hbc PCB?

The M68k hbc measures 304.8 × 243.8 mm, has 6 copper layers and is 1.6 mm thick.

How many components are on the M68k hbc?

72 components, from 36 distinct parts. The full bill of materials is listed on this page.

Where can I download the M68k hbc design files?

From the ehbc-project/ehbc-proto1-board repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the M68k hbc design in my own project?

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

Can I test firmware for the M68k hbc 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.
