Sk612-delay
About the Sk612-delay PCB
Sk612-delay is an open source ESP32 PCB design by mirdej, published on GitHub. It is a 4-layer board measuring 100 × 95 mm, with 159 components from 81 distinct parts.
Its main chip is the LMH6643, from the ESP32 family. Other key parts include the LM393, TLV3201, NE5532, C3113 and TPW4053-SR. By type, the board carries 84 capacitors, 29 resistors, 18 connectors, 11 ICs, 6 diodes and 6 inductors.
From the project
The Synkie is a modular open source analog video processor, developed by Michael Egger, Max Egger and Flo Kaufmann
The Synkie is a modular open source analog video processor, developed by Michael Egger, Max Egger and Flo Kaufmann. A bit like the venerable modular Moog synthesizer it lets you toy around with the signal using patch cables – but this time not producing sound but images. It is an instrument for video, a playground, a platform to explore new ways to transform a video signal. Synkie is still in development, we constantly develop new modules – and even the base specifications may still change over time.

Sk612-delay: common questions
What microcontroller does the Sk612-delay use?
The Sk612-delay is built around the LMH6643, from the ESP32 family.
How big is the Sk612-delay PCB?
The Sk612-delay measures 100 × 95 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Sk612-delay?
159 components, from 81 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the Sk612-delay design files?
From the mirdej/synkie repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Sk612-delay design in my own project?
The repository has no license, so all rights stay with mirdej. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Sk612-delay without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
