Modular Design and Features
The Una Watch is available for $199, offering a modular, repairable build alongside a 1.2-inch MIP LCD display and up to 10 days of battery life. The device is fully open-source, encompassing its SDK, housing, and circuit boards, and provides robust fitness tracking capabilities out of the box. Una encourages custom application development, supporting AI-assisted coding tools to help users interpret documentation and build custom software.
Modular and Open-Source Hardware
The device combines open-source accessibility with dedicated fitness tracking hardware similar to traditional sports watches.
Repairability and Customization
Every component inside the watch is accessible using standard tools, enabling users to independently repair or upgrade the hardware. Because the mechanical components are open-source, users can also design and 3D print custom mods and accessories, such as mounts to convert the watch into a cycling computer.
Hardware Specifications
The hardware includes dual-frequency GPS, 24/7 heart rate tracking, a barometric altimeter, a six-axis accelerometer and gyroscope, and a three-axis magnetometer. Power is supplied by a replaceable 280mAh battery featuring USB-C charging. Note that the device carries an IPX5 rating, meaning it is splash- and showerproof rather than fully waterproof.
