Overview
Zcd393 is an open-source printed circuit board by zoftko, from the zoftko/pcrap repository on GitHub, published under the BSD-3-Clause licence. It is a 4-layer board of 25 × 38 mm with 18 parts on 10 nets, routed with 66 tracks and 9 vias.
It is built around the LM393 and 1N5819WS. Its parts include 10 resistors, 2 connectors, 1 capacitor, 1 IC and 1 diode.
Main components
2README
cocoro/README.mdtitle: Heart shaped RGB LED Array brief: This board includes a heart shaped RGB LED array and the components to control said array through a simple user interface.
cocoro
The idea behind this board is to function as a night light. It uses an STM8s MCU to control different characteristics such as color or brightness. The user interface consists of a rotary encoder and a small I2C OLED display, based on the SD1306 controller.
Warnings
The P Channel Mosfets (FDN340P) placement to turn on the LEDs (high side switch) is wrong. Pin assignment is wrong. For example, the PCB layout marks the source as being the gate. The part needs to be rotated 90° to the left for pins to be properly placed.

Questions
How big is the Zcd393 PCB?
It measures 25 × 38 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Zcd393 use?
18 parts, built around the LM393 and 1N5819WS. 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 Zcd393 KiCad files?
From the zoftko/pcrap repository on GitHub, at the commit this page was made from: the board is zcd393/zcd393.kicad_pcb and its schematic cocoro/cocoro.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Zcd393 design in my own project?
Its repository publishes it under the BSD-3-Clause licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
