From the project
An arcade controller for rhythm games.
PH-AC is an open-source 7-button + 2-encoder arcade controller based on RP2040, optimized for rhythm/music games. Release 3.0 preserves the 7-button + 2-encoder layout while adding 3D/PCB/CAD resources, customizable RGB key lighting, and additional GPIO breakouts for easier DIY mods and mass production.
Rev3 is mainly aimed at organizing 3D, PCB and production resources and pairs with our new firmware PHAC_Firmware:

PH-AC: common questions
What microcontroller does the PH-AC use?
The PH-AC is built around the RP2040, from the RP2040/RP2350 family.
How big is the PH-AC PCB?
The PH-AC measures 200 × 100 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the PH-AC?
59 components, from 20 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 PH-AC design files?
From the ph-design/PH-AC 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 PH-AC design in my own project?
It is published under Custom license, which limits how it may be reused; read the license before building on it.
Can I test firmware for the PH-AC without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
