ZeroBoard - RP2040 Integrated Strumboard for Guitar Hero Controllers by RetroCultMods, no Pico required!

This is the Zeroboard, a Strumboard with all the fixings of a Raspberry Pi Pico integrated right into the board!

That means no more soldering 40 pins one-by-one to connect a Pico to a carrier board, which enables a much faster and smoother modding experience!

Guitar Hero controller models this board supports:

SG
Kramer
GHWT (aka "Sunburst")
Les Paul (Wii, X360, PS3)
GH5

This board includes pins for the following inputs:

-Home Button/D-Pad inputs
-Joystick Input
-Start/Select Input
-Extra Star Power Input
-Whammy Input
-Tilt Input (designed for two SW-520D tilt switches)
-Fretboard Input with support for LEDs
-Strum Up/Down Inputs
-GH5 Neck Tapbar Input
-USB Breakout for a custom connector

Programming and configuration is not needed for most games on PC, PS3/4/5, Mac, or Xbox, but can be accomplished with the programming tool listed here:

The strum switch slots are designed to fix Kailh Box switches (I use Kailh Box Navy switches, but it's all preference).

Material may need to be added to the strumbar and/or strum switches to ensure a "tight" fit, depending on the controller model.

Soldering equipment and experience required, but not included! Guitar Hero controller not included.

V1.1 Includes a few extra modules for Joysticks and Start/Select for better compatibility with certain models.

Please let me know if you have any questions!
