Programmable E-Paper Smartwatch with Bluetooth and ESP32-C Port

This watch features an E-Paper display with open-source hardware and software. It has a minimalist design that uses the PCB as the watch body, enabling it to be worn as-is or customized with 3D-printed cases and straps. It functions both as a unique timepiece and a wearable development platform. The E-Paper display delivers a crisp, high-contrast image that is clearly visible in bright sunlight and consumes no power between screen updates. With a resolution of 200 x 200 pixels and monochrome output, it offers a distinctive visual aesthetic. The watch supports Wi-Fi and Bluetooth LE connectivity, enabling integration with internet-based APIs (e.g., weather, news, traffic, maps, Spotify) and Bluetooth LE-enabled devices. Built around the ESP32 microcontroller, it benefits from strong community support and compatibility with multiple development environments, including Arduino, MicroPython, ESP-IDF, and Zephyr-RTOS. Key features include: - Ultra-low-power 1.54-inch E-Paper display with 200 x 200 resolution and wide viewing angle - Wi-Fi and Bluetooth LE connectivity - 3-axis accelerometer with gesture detection - Real-time clock with calendar and alarm functions - Built-in USB-to-serial adapter for on-the-go programming - Vibration motor for alerts - Four tactile buttons - Open-source hardware and software - Extensive collection of example projects and watch faces - Open-source 3D-printable case designs - USB-C port - Battery life: up to 1 week (3–4 days with Wi-Fi enabled) - Not waterproof - Color: Black - Material: PCB and electronic components Package includes: - 1 x Watch - 1 x Watch strap - 1 x USB-C cable
