PH60 Rev.3 is a 60% tri-mode mechanical keyboard kit with an FDM 3D-printable case and the PH60 Rev.3 Multi PCB. This revision switches to the NRF52840 MCU with Bluetooth 5.3 and Nordic 2.4 GHz proprietary protocol (TBD), runs ZMKs firmware (our fork of ZMK), and redesigns the case for wireless use and multi-layout compatibility.

PH60: common questions

What microcontroller does the PH60 use?

The PH60 is built around the nRF52840, from the Nordic nRF family.

How big is the PH60 PCB?

The PH60 measures 285 × 94.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the PH60?

204 components, from 47 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the PH60 design files?

From the ph-design/PH60 repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the PH60 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 PH60 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Nordic nRF firmware against it before you order a PCB.
