ESP32-S3 Password/Keyboard Input Dongle (USB HID)\n\n\u003e 🆕 **Latest Release – v2.1.0**  \n\u003e BLE connectivity improvements, support for additional ESP32-S3 boards (including no-display variants),\n\u003e and a restructured keyboard layout system to make localization easier.  \n\u003e See [**CHANGELOG.md**](CHANGELOG.md) for full details.\n\n## Overview\n\nThis project started as a quick prototype of a tool that makes it easier to send credentials from a mobile credentials vault app to a PC or device **without having to type them manually**. \nIt has since evolved to include companion clients (BluKeyborg) for\n[**Android**](https://github.com/larrylart/blukeyborg-android),\n[**iOS**](https://github.com/larrylart/blukeyborg-ios),\nand [**Linux**](https://github.com/larrylart/blue_keyboard/tree/main/apps/linux),\nallowing the dongle to be used as a secure keyboard or controller across platforms.\n\nIt works as a **USB HID keyboard emulator** running on ESP32-S3–based dongles and boards. The dongle receives keystrokes over Bluetooth and then \"types\" them on the connected host machine.\n\n⚠️ **Disclaimer:** This project is experimental. While basic testing has been done, bugs or quirks are likely. Contributions and improvements are welcome.\n\n---\n## 🔧 Installation \u0026 First-Time Setup\n\nQuick overview:\n- Download the firmware for your specific board / dongle\n- Flash the firmware to the device\n- Complete the initial device setup\n- Pair and provision the dongle with the BluKeyborg app\n\nFor first-time setup and provisioning, see: [**SETUP.md**](SETUP.md)\n\n---\n\n## Supported Clients\n\nThe Blue Keyboard dongle can be used with multiple companion clients across platforms.\nBelow is a list of currently supported and in-progress clients, along with their repositories.\n\n### 📱 Mobile Clients\n\n- **BluKeyborg (Android)**  \n  Android companion app and primary driver for the dongle.  \n  Handles BLE pairing, provisioning, mTLS sessions, layout management, and text/key sending.  \n  👉 https://github.com/larrylart/blukeyborg-android\n\n- **BluKeyborg (iOS)** *(pending first public release)*  \n  iOS companion app and driver for the dongle.  \n  Currently under development; first release pending additional testing and edge-case review.  \n  👉 https://github.com/larrylart/blukeyborg-ios\n\n### 🖥️ Desktop / CLI Clients\n\n- **Linux Command-Line Client**  \n  Minimal CLI client for Linux, useful for testing, scripting, and development.  \n  👉 https://github.com/larrylart/blue_keyboard/tree/main/apps/linux\n\n### 🔐 Password Manager Integrations (Related Repositories)\n\n- **KeePassDX (AIDL Integration Fork)**  \n  Experimental fork of KeePassDX implementing a clean AIDL-based output interface,  \n  allowing external HID providers (like BluKeyborg or InputStick-style devices)  \n  to integrate without embedding device-specific logic.  \n  👉 https://github.com/larrylart/KeePassDX\n\n- **KeePassDX-kb (Legacy Integration Fork)**  \n  Original KeePassDX fork with direct Blue Keyboard integration.  \n  Worked with v1 firmware; this approach is no longer actively maintained. \n  👉 https://github.com/larrylart/KeePassDX-kb\n\n- **KeePassium** – Works via the native iOS Share Sheet using **BluKeyborg (iOS)**\n\n---\n\n## Hardware\n\nBlue Keyboard / BluKeyborg runs on a range of **ESP32-S3 USB dongles and boards**, both **with** and **without** displays.\n\nThe **primary reference and development platform** is the **LilyGO S3 T-Dongle (with screen)**, but other ESP32-S3 boards are also supported.\n\nFor the complete, up-to-date list of supported hardware (including no-display and USB-C variants), see: [**HARDWARE_SUPPORTED.md**](HARDWARE_SUPPORTED.md)\n\n![LilyGO S3 T-Dongle](doc/lilygo_usb_s3_dongle_.jpg)\n---\n\n## How It Works\n\nA high-level overview of the BLE → mTLS → USB HID pipeline is available here: [**HOW_IT_WORKS.md**](HOW_IT_WORKS.md)\n\n---\n\n## Security\n\nThis project uses a layered security model (BLE bonding + application-level mTLS).\n\nFor details on the threat model, AppKey onboarding, and the mTLS protocol: [**SECURITY_OVERVIEW.md**](SECURITY_OVERVIEW.md)\n\n---\n\n## Development\n\nBuild instructions and development notes: [**DEVELOPMENT_HOWTO.md**](DEVELOPMENT_HOWTO.md)\n\n\n## Roadmap / To Do\n\n- More testing is required\n- additional fine-tuning for BLE / mTLS handshake timing (target \u003c1s connect time)\n- a more complete implementation for various keyboard layouts\n- macro support\n- optional mouse support\n- option to turn off LED / screen\n\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Flarrylart%2Fblue_keyboard","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Flarrylart%2Fblue_keyboard","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Flarrylart%2Fblue_keyboard/lists"}
