From the project

Open hardware mechanical keyboard

Open hardware mechanical keyboard, by Mário Saleiro

HacKeyboard is a mechanical keyboard built from scratch using SMK Alps Mount switches from an old Monterey K108 keyboard and Alps compatible keycaps from an old NGS keyboard.

It has several features that are not usually found in commercial keyboards: - Internal keylogger; - Macro recording capabilites; - Internal USB Hub 2.0; - Internal (hidden) 8GB flash drive; - Micro USB Port for connecting peripherals; - Customizable LED colors; - Customizable LED effects;

HacKeyboard: common questions

What microcontroller does the HacKeyboard use?

The HacKeyboard is built around the PIC18F4550_TQFP44, from the PIC family.

How big is the HacKeyboard PCB?

The HacKeyboard measures 337.8 × 118.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the HacKeyboard?

250 components, from 108 distinct parts. The full bill of materials is listed on this page.

Where can I download the HacKeyboard design files?

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

Can I use the HacKeyboard design in my own project?

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

Can I test firmware for the HacKeyboard 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.
