Wearable Firmware projects

Wearable firmware replaces or extends the PineTime smartwatch environment. InfiniTime offers a polished C++ stack with watch faces, apps, notifications, settings, Bluetooth services, and separately delivered resources. wasp-os favors a MicroPython-oriented system with a Bluetooth REPL, hackable apps, and an extended bootloader suited to sealed nRF52 watches. Choose between a daily-use firmware ecosystem and a more interactive development model rather than judging only feature lists. InfiniTime updates must be validated on the watch or they can revert after reset; wasp-os bootloader changes carry brick risk. Fully charge the watch, use the correct PineTime revision and official release artifacts, and preserve a tested recovery route before updating. Compare compatible devices, explore original projects and use the linked guides to get moving.
