Sensor Watch Pro – hackable ARM Cortex M0 brain upgrade for F-91W

The Sensor Watch Pro is a modern upgrade for the classic Casio F-91W and A158W watches, featuring a powerful ARM Cortex M0+ microcontroller. The crowdfunding campaign has raised $14,025 of its $35,000 goal, with 43 days remaining until the deadline on November 7, 2024. This innovative watch replaces the original quartz movement with a small circuit board that enhances functionality while maintaining a low power consumption, allowing it to run for over a year on a single battery. Key features include a 9-pin connector for external sensors, an RGB LED backlight, an infrared light sensor, and a louder piezo buzzer with volume control. The watch is designed for easy installation without soldering and is water-resistant, making it suitable for various activities. The Sensor Watch Pro also supports a range of customizable watch faces and applications, including fitness tracking and games, thanks to its open-source firmware. The addition of an accelerometer and a custom LCD expands its capabilities, allowing for more complex interactions and improved display options. The project aims to combine retro aesthetics with modern technology, appealing to both watch enthusiasts and tech-savvy users.
