Sensor Watch

A hackable ARM Cortex M0+ upgrade for a classic Casio wristwatch

Jan 12, 2022

Fully Funded in 23 Hours! What’s next?

Y'all, that was fast! In just 23 hours, 236 backers pledged $10,010 to bring Sensor Watch into this world — and those numbers keep climbing. Over 300 of you have ordered a watch, and some of you have ordered two! I’m blown away by the interest in this humble project, and so grateful to everyone who pledged their support to make Sensor Watch real. To be honest, I imagined this first update would be a longer deep dive into some of features of the watch, but we’ll move that to next week. For now, just a quick update about where we are and what comes next. (Also, if you’d like to see a demonstration of the latest features of the watch, I’ll be joining Adafruit’s weekly Show and Tell this evening—Wednesday, January 12th—at 7:30 PM EST. Come check it out!) Read the full update.

Our Campaign Is Now Live on Crowd Supply!

It's been a year in coming, but at last: you can back Sensor Watch on Crowd Supply and get one of your own! Sensor Watch is a board swap for the classic Casio F-91W wristwatch. It replaces the standard quartz movement with a brainy ARM Cortex M0+ microcontroller, the Microchip SAM L22, and a flexible accessory port for adding different kinds of sensors to the watch. With its extremely low power draw and classic LCD display, Sensor Watch lets you wear a hackable technology platform all year long (estimated) without recharging or replacing a battery.
