Why do people use Teensy for custom keyboards instead of Arduino boards? - ESP32 https://forum.etechnophiles.com/esp32/why-do-people-use-teensy-for-custom-keyboards-instead-of-arduino-boards/ Hi, Welcome to the eTechnophiles forum. Got a question like, \'What resistor value to choose for your simple LED project\' OR \'Where is the resistor connected to the inbuilt LED in Arduino UNO\'s schematic\' - All will be answered here. Feel free to check out the topics below. en-US Sun, 13 Sep 2026 02:08:22 +0000 wpForo 60 Answer to: Why do people use Teensy for custom keyboards instead of Arduino boards? https://forum.etechnophiles.com/esp32/why-do-people-use-teensy-for-custom-keyboards-instead-of-arduino-boards/#post-672 Wed, 27 Aug 2025 05:10:09 +0000 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.

What makes the Teensy a better choice for keyboards? Is it related to USB support, performance, or something else.
