The Cherry MX2A Red delivers a smooth, linear keypress with no tactile bump or audible click. Its consistent travel and low actuation force make it a popular choice for gaming, rapid repeated keystrokes, and users who prefer an uninterrupted keystroke from top to bottom with a 100-million actuation lifespan.  
The MX2A generation builds on the reliable Cherry MX design with factory-applied lubrication, an optimized spring, and refined housing geometry to provide smoother key travel, reduced spring noise, and improved typing feel while maintaining compatibility with standard MX keycaps and PCBs. 

The Cherry MX2A Blue combines a tactile bump with a distinct audible click at the actuation point, providing both physical and audible feedback with every keypress. It is well-suited for users who enjoy a traditional mechanical keyboard feel and want clear confirmation that a key has been actuated with a 50-million actuation lifespan. 

The Cherry MX2A Brown provides a tactile bump without an audible click, giving users physical feedback as the key actuates while remaining relatively quiet. This makes it well-suited for general typing, programming, and mixed gaming applications where tactile confirmation is preferred without the additional noise of clicky switches with a 100-million actuation lifespan. 

This specialized breakout board bridges the gap between the unique physical footprint of a Cherry MX or Cherry MX2A mechanical keyswitch and standard breadboard or matrixed layouts. Whether you are building a simple single-key macro input or a full-sized keyboard layout, this breakout takes the anxiety and complexity out of the equation!

On Teensy 4.x, [const] doesn't always mean what you might expect. It tells the compiler that your data shouldn't be modified, but it does not automatically mean the data will live only in flash. In this week's Paul's Deep Dives, he'll show you how to correctly store both your lookup table and its strings in flash.
