ESP32 Bluetooth WiFi Smart Watch w/ Touchscreen, Step Counter, Accelerometer, Gesture Sensor


  • Easily get started with code that runs on a smartwatch
  • Rechargeable, with a built-in USB to Serial (CP2104) chip, it’s ready for programming out of the box
  • Includes a BMA423 accelerometer, a vibrating motor, a capacitive touchscreen, an RTC, and a rotary encoder for controlling its functionality
  • Compatible with Arduino and MicroPython



The T-Watch is an electronics tinkerer dream! A fully programmable smartwatch that requires no messy wiring or additional components to get started — it carries its own CP2104 USB to Serial chip. Just pop out the micro-USB metallic cover and connect it to a computer for modifying its default firmware or loading up your own code. Powered by an ESP32 dual-core wireless System-on-Chip (SoC) with 520KB SRAM, this smartwatch is fully programmable and customizable.

Inside, the smartwatch has a built-in ceramic WiFi/Bluetooth antenna for improved signal quality. Outside, it offers access to a beautiful, 1.54-inch LCD capacitive touch screen (ST7789 driver) and a clickable rotary encoder (built-in push button).

The T-Watch also features onboard sensors that communicate their readings to the ESP32 SoC. These include a BMA423 3-axis accelerometer to measure movement whose measurements are used by built-in step counting, activity recognition/tracking, and advanced gesture recognition algorithms. Additionally, a vibrating motor can be controlled for notification purposes. The smartwatch also carries a 55 mAh rechargeable lithium battery.


  • Easily get started with code that runs on a smartwatch. With a built-in CP2104 USB to Serial chip, it’s ready to plug and program!
  • Powered by an ESP32, this smartwatch is compatible with a wide array of Arduino and IDF libraries
  • The T-Watch’s capacitive touch screen is a great way to practice and improve your User Interface (UI) skills
  • The onboard BMA423 accelerometer provides the necessary data for counting steps, tracking activity, and more!
