The project is an MCU based smartwatch. The MCU which is used is the ATMEGA32U4. The whole project is powered with the 3.7V 380mAh LQ-S1 lithium battery. I am also using an TFT 240 x 240 IPS ST7789 display with SPI. And the RV-3028-C7 Extreme Low Power RTC Module with I2C. In future revisions, an accelerometer will be added.
