View original source ↗What it is:
Watchy is a fully open-source E-Ink smartwatch whose hardware designs and firmware are publicly available. Finished products and accessories are still officially sold through channels including Mouser, The Pi Hut, and Crowd Supply, making it a rare wearable-hardware project that is both open source and directly available as a finished product.
Hardware list and approximate cost:
The core hardware consists of an E-Ink display paired with an ESP32 controller. This repository’s README does not provide a detailed list of the exact models, PCB design, or structural BOM; consult the official documentation at watchy.sqfmi.com for the complete technical details. Finished products or accessories, including cases and watch bands, can be purchased directly through official channels. This repository serves more as an entry page than a complete tutorial.
Overview of replication steps:
1. Purchase a finished Watchy or component kit from Mouser, The Pi Hut, or Crowd Supply
2. Open the Getting Started documentation at watchy.sqfmi.com and configure the development environment
3. Flash the official firmware, or use the open-source code to create your own watch face/App
4. If you need case accessories, purchase them separately from shop.sqfmi.com
5. Ask questions in the official Discord community if you encounter problems
Getting-started advice:
This GitHub repository contains very little information. The actual firmware code, schematics, and detailed tutorials are all on the documentation site at watchy.sqfmi.com. Review the complete documentation there before deciding whether to begin the project.Models & stability
