README
README.mdESP Clock
ESPC stands for ESP Clock and is a digital IoT clock. It's connected to WiFi, automatically syncs time, shows weather information, and most importantly, has RGB! At its core, there is an ESP8266, and the display is made of WS2812B LEDs.
It's a project I've been working on over the past few years, and it has allowed me to learn a lot about the C language and PCB designs.
This project consists of multiple repositories:
- espc-firmware
- espc-hardware
- espc-python-client
- espc-dev-tools
ESP Clock Hardware
This repository contains the PCB and 3d models for the ESPC.

Questions
How big is the Clock PCB?
It measures 284.5 × 106.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Clock use?
72 parts, built around the ESP-WROOM-02, AMS1117-3.3, WS2812B and U254-051T-4BH81-S1S. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Clock KiCad files?
From the Yanndroid/espc-hardware repository on GitHub, at the commit this page was made from: the board is pcb/clock.kicad_pcb and its schematic pcb/clock.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Clock design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
