What is it?

This watch is a multifunctional programmable watch that I have specially designed for IoT developers, electronics enthusiasts, and learners of cybersecurity attack and defense.It is equipped with an ESP32S3 chip, a 1.8-inch color screen, a 1000mAh battery, and various expansion interfaces(SPI,IIC,UART). The main controller of this watch is ESP32S3N16R8. It has 16MB Flash and 8MB PSRAM. ESP32-S3 is a dual-core XTensa LX7 MCU, capable of running at 240 MHz. Apart from its 512 KB of internal SRAM, it also comes with integrated 2.4 GHz, 802.11 b/g/n Wi-Fi and Bluetooth 5 (LE) connectivity that provides long-range support.

What makes it special?

• High-brightness and colorful screen display :1.8-inch ST7735 TFT color screen (128×160 resolution) Supports RGB565 color display, dynamic display of time, sensor data and custom interfaces.
• Transparent plastic shell : Balancing lightweight and circuit visualization, with optimized light transmittance design.
• High-capacity battery ：1000mAh battery ensures long-lasting power supply
• External IPEX rubber rod antenna ： Signal strength enhanced by 30%, optimizing the stability of long-distance WiFi communication and the performance of attack and defense tests.
• SD card expansion slot ：Local storage of log data/firmware/resource files is available.
• WS2812B full-color LED ： Supports over 30 color changes, programmable display status/alarm/personalized breathing light effects.
• Buzzer: Support PWM tone output for event alerts or attack and defense test feedback.
• Dual-button + rotary switch:Support short press/long press/rotation operations to build flexible interaction logic.
• Built in RTC : The built-in DS3231 clock chip can be customized to set the time.
• The built-in battery voltage monitoring pin can monitor the battery power at any time.

Development advantages

• Compatible with development frameworks such as Arduino (ESP32-S3-DevKitC), MicroPython, and ESP-IDF, and supports one-click code burning.
• The TF card comes with a series of sample codes, making it convenient for quick learning upon receiving.
• High-performance chips with antennas are also suitable for advanced scenarios such as learning Wi-Fi attack and defense.

Applicable scenarios

• Learn FreeRTOS task scheduling, WiFi networking, and OTA remote upgrade.
• Support MQTT/HTTP protocols to achieve cloud data synchronization.
• Analysis of WiFi Protocol Vulnerabilities (such as Defense against Deauth Attacks)
• Build a portable wireless signal monitoring device
• Customize the watch face UI to achieve personalized clock/sports tracker.
• Develop gesture interaction functions in combination with the motion sensor.
