Watchy Pebble-like Smartwatch with E-paper display, ESP32 processor launched on Crowd Supply

Pebble smartwatch was introduced in 2012 on Kickstarter. The Bluetooth smartwatch came with an E-Paper display, would connect to your Android smartphone or iPhone to receive notifications or other info, and the company also released an SDK for further customization. It was quite popular at the time having sold over one million units, the Pebble Time followed in 2015 with a color display, as well as other models. But despite selling millions of watches, the company folded in 2016, and the Pebble was discontinued after the intellectual property was purchased by Fitbit.

Watchy is a new smartwatch that reminds me of the original pebble. It is based on ESP32 WiFi & Bluetooth SoC, equipped with a 1.54-inch E-Paper display with 200×200 resolution, and the usual accelerometer for activity tracking and gesture detection.

Watchy smartwatch kit

Watchy sells as a kit with a fully assembled Watchy PCB, the E-Paper display, a 200mAh Battery, two adhesive tapes, and a watch strap.

The smartwatch is open-source hardware & software with documentation, KiCad hardware design files, 3D Case Designs (STLs), and plenty of examples and watch faces on either the product page or Github released under an MIT license. The watch is said to support Arduino, MicroPython, and the ESP-IDF framework.

Watchy used to sold by SQFMI on Tindie for a low as $44.99 but sadly is currently out of stock, and instead, the Watch has now launched on Crowd Supply for $49.99 with free shipping to the US.
