ESP32-S3 USB HID Keyboard Kit - Build Your Own Macro Keypad with 8 Programmable Buttons

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Transform an ESP32-S3 into a fully customizable USB macro keyboard that types entire email templates, executes complex keyboard shortcuts, or launches apps with a single button press. No driver installation required - just plug it into any computer, and it appears as a native HID keyboard. Whether you're a streamer wanting quick OBS scene switches, a programmer tired of typing the same boilerplate, or a student building a project for your school exhibition, this kit puts a professional macro pad on your desk in an afternoon.

What You'll Build

A compact 8-button keypad that sends any keystroke or string you program. Each button can be assigned a unique macro - a whole paragraph of text, Ctrl+C/V combos, media controls, or custom shortcuts like Alt+Tab. The three LEDs provide visual feedback on which layer or profile is active. You'll have a finished, ready-to-use device that improves your daily workflow, all built with your own hands.

What You'll Learn

• Configure the ESP32-S3's native USB interface to act as a Human Interface Device (HID) keyboard
• Write Arduino IDE code that detects button presses and sends matching keystrokes
• Implement debounce logic and key rollover for reliable typing
• Add LED indicator patterns to display keyboard layer or macro status
