About the Keyface PCB

Keyface is an open source PIC PCB design by z00m128, published on GitHub under the CC-BY-NC-4.0 license. It is a 2-layer board measuring 66.7 × 60.3 mm, with 37 components from 16 distinct parts.

Its main chip is the PIC16F84, from the PIC family. Other key parts include the MHB8804, 74LS125 and 74LS32. By type, the board carries 15 resistors, 7 capacitors, 5 ICs, 4 diodes, 2 transformers and 1 transistor.

Keyface: common questions

What microcontroller does the Keyface use?

The Keyface is built around the PIC16F84, from the PIC family.

How big is the Keyface PCB?

The Keyface measures 66.7 × 60.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Keyface?

37 components, from 16 distinct parts. The full bill of materials is listed on this page.

Where can I download the Keyface design files?

From the z00m128/pcb-resources repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Keyface design in my own project?

It is published under CC-BY-NC-4.0, which limits how it may be reused; read the license before building on it.

Can I test firmware for the Keyface 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.
