ProGCC 3S Main PCB - Wired Only Competitive Conversion Kit

For competitive play, just one moment of wireless lag or interference can mean everything.

Enter ProGCC 3S - a drop-in PCB conversion kit designed from the ground up for wired performance.

This is the newest version of the ProGCC as of 2026. It is powered by the Raspberry Pi RP2350 microcontroller.

This is the wired-only version of our ProGCC main board. This board is compatible with OEM button PCBs and other parts.

What is frame-sync? The Nintendo Switch operates at 60fps. This is equal to a 16.666ms refresh rate. USB inputs are typically performed at 8ms. This leads to a desync between the USB input rate and the framerate of the game. Our custom firmware dynamically adjusts the USB input rate to perfectly match the framerate of your games, leading to 99% perfection with your input spacing.
