Product detailed description

Development kit for wearable electronics in the shape and size of a watch. The kit is based on the ESP32 microcontroller clocked at 240MHz, which includes WiFi and Bluetooth. Also included on the kit board is a BMA423 3-axis accelerometer, a PCF8563 real-time clock and an I/O connector for connecting external devices/sensors. Power is provided by an integrated 3.7V Li-ION battery that is charged via a USB-C connector. The kit also includes two buttons, one of which is for on/off and the other is programmable. The kit does not include a touch layer on the display.

FreeRTOS is used as the operating system. Programming is done via the USB-C connector.

There are 6 sensors included with the watch:

  1. Button
  2. PIR sensor
  3. Door contact
  4. Microphone
  5. DHT12 sensor
  6. 4x intelligent RGB LED WS2812
