This repository contains the schematics and board layouts for Eagle of the different DaClock versions I've done so far. The common parts between all these versions are: a microcontroller on board with some power management, an RTC and connectors for LED strips or matrices.
Current version is 3.0, based on ESP8266 and DS1337S, also features a buzzer and support for both WS2812 strips/matrices and 5050 "single color" strips.
This is the latest version of the DA CLOCK board, a custom ESP8266-based clock with an RTC, a buzzer and output to handle WS2812 strips.
