Overview
WeckerMk2 PCB is an open-source printed circuit board by munilabdev, from the munilabdev/Alarmclock_Mk2 repository on GitHub, published under the MIT licence. It is a 2-layer board of 85.8 × 43.5 mm with 12 parts on 50 nets, routed with 150 tracks and 11 vias.
It is built around the ESP32-DEVKITC-VE. Its parts include 6 resistors, 1 IC and 1 switch. It belongs with the ESP32 boards of this library.

Second prototype of my adhan- and alarmclock
What is the Alarmclock_Mk2?
The Alarmclock_Mk2 is the second prototype of a self-designed alarmclock, which shows the time and date, the next prayertime, and plays the Adhan and a alarm, if the time has come.
I used an ESP32 as the microcontroller, a MAX98357A as the amplifier, a 1.3" OLED, a SD-module and a rotary-encoder for input.
Available are code and pcb-files made in KiCad, available to use via MIT License.
There are still some flaws, for example bouncing of the rotary-encoder, which are intended to be adressed in Mk3, which will be started soon.
I would be glad about feedback and criticism.
Thank you.

Questions
How big is the WeckerMk2 PCB PCB?
It measures 85.8 × 43.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the WeckerMk2 PCB use?
12 parts, built around the ESP32-DEVKITC-VE. 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 WeckerMk2 PCB KiCad files?
From the munilabdev/Alarmclock_Mk2 repository on GitHub, at the commit this page was made from: the board is PCB/WeckerMk2_PCB.kicad_pcb and its schematic PCB/WeckerMk2_PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the WeckerMk2 PCB design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
