About the ESP32C3 Watch PCB

ESP32C3 Watch is an open source PCB design by k-ying, published on GitHub. It is a 2-layer board measuring 42 × 42 mm, with 53 components from 27 distinct parts.

Other key parts include the TP4056, XC6206-1.8, TC1262-33, MAX30102 and CH340C. By type, the board carries 19 resistors, 14 capacitors, 7 ICs, 7 connectors, 4 diodes and 1 switch.

It belongs with the wearables, iot & wireless and sensors designs in this gallery.

From the project

The smartwatch made based on ESP32-C3(RISC-V MCU), which has heart rate, oximetry, temperature, fall detection and IOT Function. 基于 ESP32-C3的智能手表（RISC-V MCU），具有心率、血氧饱和度、温度、跌倒检测和物联网功能。

The project stems from My Graduation Project in 2022, Since the time for secrecy has ended, I can open source its design and code.The project may be very old, some components and functions can not be used directly, need to be adjusted according to the latest library, please be aware of.

Here are the folder descriptions: 1. HardWare: used to store hardware related, circuit design and PCB design, using KiCAD for the design of the project; also contains 3D models and peripherals DataSheet. 2. Software: used to store the programme code of CMU master control, this project uses ESP-IDF (LVGL…
