Overview

### Introduction:

A smart watch based on stm32F411CEU6, using the open source embedded UI framework LittleGL to create an interface with a beautiful and clear interface.
This project is based on the open source smart watch WatchX, Github address: [https://github.com/FASTSHIFT/WatchX](https://github.com/FASTSHIFT/WatchX)

### **Hardware configuration:**

* 1. Main control: STM32F411CEU6 (clock: 100MHz RAM: 128KB ROM: 512KB)
* 2. Screen: ST7789 IPS 1.14inch SPI interface 135x240 resolution 100Hz refresh rate
* 3. Input device: buttons x3
* 4.RTC: MCU built-in RTC clock
* 7. Power management: TP4056 + TPS63070
