GoKawiilUna launches modular, repairable GPS running watch with open-source design
Una has released a 46mm GPS running watch built from six separate, user-replaceable modules held together with Torx T3 screws, including distinct display, GPS, Bluetooth, PPG sensor and core compute modules. The core runs a Cortex-M33 microcontroller with 2.5MB of RAM and 4GB of eMMC storage on FreeRTOS, and Una has published its software, housing and circuit board designs on GitHub alongside a developer forum.
GoKawiil's interpretation of the reporting above, not reported fact.
By publishing hardware and software designs openly, Una is inviting tinkerers and developers to modify or repair the watch rather than replace it, which could extend its usable life and reduce e-waste compared with sealed competitors like Garmin or Suunto. The modest, low-power hardware suggests Una is prioritizing repairability and openness over raw performance, a tradeoff that may appeal to a niche of open-source enthusiasts even as it limits mainstream appeal.
