TofuPad - Symmetrical leverless style controller

Tofupad is a free diy symmetrical slim low-profile hitbox/leverless style rhythm game controller that uses a YD-RP2040 Raspberry Pi Pico clone with USB-C and the GP2040-CE controller firmware.

Created primarily with DJMAX and Taiko No Tatsujin in mind, but should be compatable with a galaxy of other rhythm games.

Parts required

• 1x YD-RP2040
• 9x M4 x 8mm Hex Socket Countersunk Head Screw Bolts
• 12x low profile gatreon keyboard microswitches of your choice
• a 3D printer with a 10 inch printbed or access to a 3D printing / CNC milling service(JLPCB, PCBWAY, etc)

This case is sized exactly for this particular flavor of Pico clone and while others may fit, they will likely be loose in the socket leading to issues plugging in the USB. In addition, most low profile microswitches should work, but full sized will be too tall to fit without removing part or most of the legs.

You may also want to try microswitches that have a lower actuation point. Most low profile linears have a really high actuation point and can make pressing buttons feel a little akward, since they will activate as soon as you touch the button rather than when you're close to bottoming out like most traditional rhythm game microswitches do. Consider possibly a tactile switch to help with this.

This project presupposes at least an intermediate soldering level as solding to microswitch legs and routing wires in such a tight environment may be difficult without some experience.
