Not every smartwatch needs to have an AMOLED display and a $300+ price tag. The new Watchy smartwatch from SQFMI is a simple, cheap, and hacker-friendly smartwatch that uses a square E Ink display, an ESP32-S system-on-a-chip, an accelerometer, and 4 buttons plus a vibration motor.
It’s programmable with support for Python and Arduino. And the whole thing costs just $55.
Watchy’s key components include a 200 x 200 pixel E Ink display, and that ESP32-S module, which features a low-power dual-core processor and WiFi and Bluetooth. SQFMI says the watch should get up to 2 weeks of battery life from a charge, and there’s an integrated DS3231 real-time clock which should help keep time.
There’s also a BMA423 MEMS accelerometer with support for step counting and gesture recognition.
