Bangle.js 3 Smartwatch, Digi Mart USA News: The team behind the open-source Bangle.js smartwatch has published images and detailed specifications for the Bangle.js 3, the successor to the Bangle.js 2 released in 2021. The company expects the watch to launch in summer 2027, although pricing has not yet been announced.
The most visible change is the display. The rectangular screen of the predecessor is replaced by a round 1.2-inch LCD with a resolution of 240 x 240 pixels and support for 64 colours.
Thinner bezels and a metal bezel give the watch a more modern look than the Bangle.js 2, according to the publisher’s report.
The Bangle.js 3 includes speakers, microphones, a vibration motor and a heart rate sensor. It does not include more advanced health sensors, a GPS module or an NFC chip.
Instead, it adds a Bosch gas sensor designed to detect certain smells, along with an LED flashlight.
The watch uses a roughly 200 mAh battery that is charged wirelessly. Its open-source operating system allows the community to expand its functionality.
The case can be opened with a few screws, and four pins provide power and data connections for diagnostic and programming purposes.
The device is powered by an ARM Cortex M33 (nRF54L15) processor running at up to 128 MHz, with Bluetooth Low Energy and 32 MB of memory. The report describes the watch as not particularly powerful, but says it should offer relatively long battery life.
