I’ve seen many DIY keyboard projects where people use a Teensy microcontroller rather than popular Arduino boards like the Uno, Nano, or Pro Mini. What makes the Teensy a better choice for keyboards? Is it related to USB support, performance, or something else.

The main reason Teensy is preferred for DIY keyboards is its native USB support. Unlike most Arduino boards (like Uno, Nano, Pro Mini) that use a separate USB-to-serial chip, Teensy’s microcontrollers handle USB directly.
This allows them to appear as a true USB HID device (keyboard, mouse, MIDI, etc.) without extra work.
On top of that, Teensy boards generally offer more flash, RAM, and faster processors, which makes them well-suited for complex keyboard firmware like QMK or TMK that require custom layouts, macros, and lighting effects.
The Arduino Uno/Nano can’t natively emulate a keyboard without workarounds, while Teensy supports it out of the box.
